I did a piezoelectric test with a digital oscilloscope and when I hit it with my hand only once I saw it rise and fall several times instead of just once. Immediately after the impact was stopped, the output was stable, but during the impact, it seemed as if there were several impacts. Does anyone know why? Why are multiple outputs recorded? And what is the solution?
The image on the left of each peak shows the increase in output during each hit. In the enlarged image on the right, you can see the image on the left that the voltage has reached its maximum and minimum in each stroke about 10-12 times.
Relevant answer
Answer
It is coming from the electric line frequency. If you will do FFT of this data you will get the corresponding frequency. Find proper grounding and device isolation for minimal stray signals.

I'm doing Surface Plasmon Resonance for a series of samples with different concentration starting with lowest concentration. Binding is so strong that I cannot reach the baseline after washing step with running buffer. Each time just part of binding dissociate. And then I test the next concentration. Several regeneration solutions have been tested but nothing could bring the signal to the baseline.
I use a Reichert SPR device and use Scrubber for analyzing the data.
How can I interpret these data in Scrubber, without a complete dissociation and/or regeneration?
Any thought would be highly appreciated.
Relevant answer
Answer
Hi Nelly. I think it is going to be difficult. Without regeneration and complete dissociation you are basically performing a so called single cycle kinetics experiments which is a patented approach and therefore, data analysis is not available. You could run low but non-zero concentrations in between your concentration series and use TraceDrawer. Alternatively, you could use Interaction map for data analysis. Best, Jos

We know that for each and every action, there is an equal and opposite reaction. For advanced wireless sensor technology, I developed a formula: “Due to the active sensor technology, every human, animal or object is affected by the processed radio frequencies of its movement through electromagnetic transmission within the boundaries of the body in the GPS positions and GNSS distances. This effect is proportional to its weight factors and disproportionate to its GPS positions and GNSS distances. As a result, the person, animal or object is damaged by the changing waves and for recovery systems, the living object should change instantly from the existing location with tightly closed eyes”

Stomach cancer has an unimaginably important place in the incidence of cancer and cancer-related deaths worldwide. Different studies have different opinions about its origin, some say it is due to alcohol and smoking, others say that it is due to fried food, some say it is due to Helicobacter pylori. But no one mentions the main reason, which my research has revealed. Today we can explain about Stomach Cancer with ISNAH (Impact of Sensor Networks towards Animals and Humans), CASSID (Common Acute Sensor Sudden Infection and Disorder) and CDRAST (Cancer Disease Recovery through Advanced Sensor Technology), which will help to know the theme of in-body GPS sensor.

I need to know the best type of bi-potentiostat instrument?
Relevant answer
Answer
A potentiostat is the electronic hardware required to control a three electrode cell and run most electroanalytical experiments. A Bipotentiostat and polypotentiostat are potentiostats capable of controlling two working electrodes and more than two working electrodes, respectively. In order to measure the I-V of the electrode one drives a constant current in it till the required potential between the electrode and the reference electrode is reached this is accomplished by the potentiostat. Since the reference electrode does no conduct any current and its function is to sense the potential of the electrolyte only, the current in the working electrode must continue flowing in the counter electrode.

Hello,
I have several sensors which are interfaced with the help of ROS and are synchronized with the ROS time(ROS1). The sensors and their nodes are fully functional. Each sensor does some processing ,after it senses a detection in it's environment, before eventually timestamping this data in ROS. Since the sensors are of different kinds, and have their own processing before eventually timestamping it's data in ROS, there is an expected delay between the detection and the timestamping and also a delay is expected between the different sensors.
I am interested in the delay that takes place between the sensor detecting an event and eventually timestamping this data in ROS. The image shows the different processing for each sensor that takes place before timestamping.
When searching for this specific problem not much could be found, so any advice would be appreciated.

I want to measure the curvedness of that solar mirror , and i have this idea of putting several distance sensors on the line to get different distances on those positions so i can put them on a graph .
The difference between them is very smal (around 1mm each ) so maybe i should go for more accurate sensors
Is it the right way to do it or you can suggest me other methods or other better sensors ?
Thanks in advance.
Relevant answer
Answer
take a small led with a wide output angle and place it behind a small hole in a screen. then shine the LED onto your mirror and look for the reflection of the LED on the screen. Change the distance between the screen and the mirror until you get the smallest image line of the reflected LED light on the screen.
You of course will not get a spot but a line because you have a cylindrical mirror
Hold the screen so that the reflected beam comes back close to the hole you have made for the LED to shine through.
When you have the narrowest line, your screen is in the plane at the center of he curvature of the mirror.

Question

As recently concluded in a parallel discussion, see reference below, LIGO is unable to exclude that mirror displacements as observed along their interferometer arms in fact result from much larger mirror displacements of similar profile along the vertical.
This is because mirror suspensions act along the vertical which over a distance of 4 km varies by an angle of about 2 arc min (a nautic mile = 1,852 m by definition corresponds to 1 arc min of angular distance at sea level). So every vertical mirror displacement will exhibit a displacement component about three orders of magnitude smaller along the connecting interferometer tube.
As LIGO is unable to directly measure vertical mirror displacements with adequate sensitivity they cannot distinguish whether horizontal displacements such as assigned to gravitational wave interaction are due to horizontal excitation or to vertical excitation at three orders of magnitude larger amplitudes.

Hi,
i am currently trying to approximate the distance of a sensor when being moved. I am recording all the raw sensor data for later analysis with python.
Those values are 16bit for XYZ-axis as well as an timestamp.
I am working with a discrimination window to neutralize all values which are below a calibrated threshold-value. Also I am using a butterworth lowpass with a 6Hz cutoff frequency.
When integrating the acceleration data twice my distance value is very far off.
I read a lot of the filtering already and that its very application-oriented but I am not really sure where I should start from right now.
Thanks for your help already.
Relevant answer
Answer
To get position you have to integrate the acceleration twice. Each time you integrate you introduce a constant, the first time the starting velocity, and the second time the starting position. The integration does not know what these are and unless you specify or force them to be the correct value then they could be anything, and you will get a drift velocity and a position offset unless you are very lucky.
If you are using a filter to do the integration, it will introduce its own offset, so you need to find out what that is and if it is wrong, put in a correction term. If the filter is not DC coupled the velocity offset will be the negative of the mean acceleration times the time, minus whatever the starting velocity was.
The same will happen with the second integration, but you probably are not worried about where the start position is, yet, as you are mostly looking at the velocity.

I'm looking at the datasheet of the MiCS-6814 from Sensortech, and it says it measures Ammonia, Carbon Monoxide, Ethanol, Hydrogen, Iso-Butane, Methane, Nitrogen Dioxide, Propane but it has only 3 sensing elements (RED, NH3, OX). Looking at the profiles, there's multiple gasses there at different or sometimes overlapping ppm concentrations.
For example, for the NH3 (Ammonia) sensing element, it also overlaps hydrogen. Do I need to calibrate the sensors to sense only that type of gas using a gas chamber? Is it possible to sense all of the gasses in a 1 hour period? For example first 5-10 minutes Ammonia, then Hydrogen, etc.?

In my openion, the chemical industry is one of the most important industries in the world. Not only do 90% of our everyday products contain chemicals, but the industry also employs approximately 10 million people. Naturally, they were one of the first to embrace digital technologies such as process control systems or sensors which have a long tradition in production.
A continuous digital transformation plays a crucial role in several key aspects of the industry. Accenture has identified the six most influenced areas.
  • Higher Levels of Efficiency and Productivity
Increase competitive advantages and further decreases the costs through operational optimizations.
  • Innovation through Digitalization
Helps boost the productivity in R&D and thus decrease the time till market entry.
  • Data Management and Analytics
An improved understanding of customer needs and so the optimization of offerings are integral contributors to any company’s success.
  • Impact on the Workforce
Tasks and opportunities, as well as the job requirements, will experience a change with digital transformation. “Finally, technology will take an even greater role in upskilling and training employees, and in knowledge management.” (World Economic Forum & Accenture, 2017)
  • Digitally enhanced offerings
An increasingly important aspect of product performance especially for close-to-end customer markets.
  • Digital Ecosystems
Being separated into Innovation, Supply and Delivery, and Offering Ecosystem.
Industry 4.0, however, does not only include aspects of digitalization but mainly artificial intelligence, robotics, Internet of Things (IoT) or advanced materials. In the table below their impact on chemical products is illustrated.

Given the current advances in Green IoT and Sensor Technologies, the practical applications in farming and agriculture are more common.
Relevant answer
Answer
Hello,
I think the Big technical challenge for Measure & Estimate the Humidity and Rain Drop for Farming is "Design ultra-low power and cost-effective wireless sensor node".
Also, system designer needs think on following points.
1. This system is always deployed outdoor location and needs to measure Open Air Humidity. It is hard to find weatherproof humidity sensor, Only SHT20 I2C Temperature & Humidity Sensor (Waterproof Probe) is available but this is not cost effective because the user is a farmer and for farmer need the cost-effective solution. low-cost alternative for this is weather/ instrument shelter but it should have very good air circulation then we get perfect humidity.
2. Expected battery backup is more than 9 Months so that solar panel cost will be reduced. To develop ultra-low power designer needs to implement dynamic sleep and data transmission algorithm.
3. if we consider power consumption is the main factor then GSM is not a good choice. NBIoT, LORAWAN is the best choice for that. NBIoT not launched yet in all countries.
4. network latency, QoS, Sensor reliability and accuracy and overall Sensor node cost and size.

If so which company is good for this purpose.
Can someone name model number and company name
Relevant answer
Answer
In a common case (the sensor response is from 0 to 10....) you have to verify, in this order, that:
- at least one of the measuring range of the instrument covers the measured values range (sensitivity criterion)
- the input impedance of the instrument is high enough to be compatible with the impedance/resistance of the sensor/measuring circuit (impedance compatibility criterion); a "basic" instrument may fail this criterion,
- the resolution/readability of the instrument is the observed response precision of the sensor (consider here the relative standard deviation of the recordings) plus 1 digit (resolution criterion),
The difficult case is when you have to measure a small variation
Δx of a high value X. The best solution is to use a differential measurement (in this case you will also measure from 0 to 10....); if this is not possible, a high resolution (many digits) instrument is needed.

I want to use 4 accelerometers in an experiment. I will be using a raspberry pi. How can I distinguish the data from each sensor?
This is the accelerometer I am using http://uk.rs-online.com/web/p/products/9054665/
There are 2 addresses... does this mean that only 2 accelerometers can be connected to the raspberry pi?
Relevant answer
Answer
Minor correction to Bhaskar Ghosh's post:
  1. You can have only 2 of Adafruit's accelerometers at a single I2C line (as the I2C addresses of this accelerometer differ only in a single bit).
  2. As the RPi has got 2 I2C interfaces, you can connect 2 * 2 accelerometers - 2 at each I2C line (provided there's nothing else attached that's interfering with these).
The differentiation between every 2 of these accelerometers is via the address bit in the communication frame (for details see the Adafruit / accelerometer chip documentation): your commands are issued for one of the two accelerometers - depending on the address bit. The accelerometer addressed will "answer" while the other one will stay "silent".

Relevant answer
Answer
BH43-3D TDEM PROBE
In conjunction with a ground-based PROTEM system, the BH43-3D provides three-dimensional time domain electromagnetic data from boreholes. With a 500 x 500 m transmitter loop at surface, data can be received from boreholes to depths of 2.5 kilometres. (At developed mines, the transmitter loop can be laid out within the underground workings.) The BH43-3D probe has three sensors that measure orthogonal components of decay. Measurement intervals are determined by the resolution required; along the hole, spatial resolution as fine as 1 m can be obtained. The wide bandwidth of the probe, coupled with the excellent temporal resolution and large dynamic range of the PROTEM system, provides maximum diagnostic information and a high degree of rejection of powerline and other sources of noise.
The BH43-3D probe is available separately, or as a complete borehole system with cable, main winch, dummy probe, test cable and winch, and retrieval tools.
MAG43-3D FLUXGATE PROBE
MAG43-3D probe is an ideal tool for the survey of highly conductive targets such as nickel sulphide ore bodies. While such targets may produce very little decay to measure with an induction coil, strong secondary magnetic fields can be readily detected with a fluxgate sensor. As with the BH43-3D, measurements from depths to 2.5 km are achievable.

Dear Sir/Mam,
Recently I have completed my PhD in Physics (SnO2 as a gas sensor). Now I need to write some project. I plan to work further in the field of gas sensing. Offcourse, I understand that I need to write a project on my own. My expertise in gas sensing is probably lesser then many in the field. Can someone suggest me some ideas (problem statement) so that I can write a acceptable project which can contribute to substantial improvement of present sensing technology?
Thanks and regards
Relevant answer
Answer
The most important problem with SnO2 gas sensors is some lack of sensitivity to the individual gases - eventually paired with some lack of robustness (and eventually sensitivity) in oxygen-depleted atmospheres. If you feel you can contribute to either or both of these topics: be invited!

Available CCD image sensors is restricted to 400-1100 nm range. Is it possible to get a this for 2 um range. What difficulties it encountered to develop such sensor ?
Relevant answer
Answer
Mercury Cadmium Telluride is probably the go-to material at this wavelength. InGaAs imaging arrays are also available, though MCT are "state of the art," I suppose. The ordinary ones, with the spectral sensitivity in the 400-1100 nm are based on Silicon.
The difficulties with both MCT and InGaAs are much higher noise than Silicon, and sensitivity to background thermal radiation. They generally require cooling (down into cryogenic range) and shielding. They are also difficult materials to work with, so processing is much harder than for Silicon.
Another established manufacturer in this area is Teledyne.

What could cause damage to the sensitive layer in mt-500 gas sensor?
and how we can fix that?
Relevant answer
Answer
Was the sensor packaged "hermetically sealed" - eventually with some desiccant bag? 60 °C shouldn't damage the device and dirt should not be an issue if packaged in some plastics. Humidity could be an issue if not hermetically sealed.
Another topic: is the device "completely dead" ?
I looked into the manual and found that it should suffice to connect the supply (24 V DC, connector position #4) and ground ("0 V", pos. #11). While the sensor might be reverse polarity protected, it will not work if polarity is reversed. Depending on the state of your wire connection, it might help to check the supply directly at the connector with a multimeter.

I am working with a CS105 pressure sensor and I would like to exactly how changes in capacitance are measured, communicated via an electronic signal, and then interpreted as a change in pressure. I understand the principles of the device but I cannot find documentation that has information about how a signal is generated after a reading, and how signals differ based on different readings.
Relevant answer
Answer
Regarding the "raw" capacitive pressure sensors, the sensing capacitor typically is part of a tank circuit oscillator. Thus any change in capacitance results in a change of the frequency of the oscillator that can be measured.
Regarding the CS105, there is obviously more electronics inside to evaluate the signal - most likely some microcontroller that does signal evaluation/conditioning.
Data sheets and application notes of pressure sensor chips (more or less all big semiconductor manufacturers have such) might helps you to understand the complete signal chain. Use google or the search engine of your choice to proceed...

I have been trying to plot the detection efficiency of polyethylene (the conversion layer we are using to detect fast neutrons >1 MeV) for various thickness (1300 and 2000 microns) and compare the detection efficiency when no conversion layer is used (Silicon) from the simulated data obtained by scoring the energy deposited in every pixel of a hybrid detector modeled in FLUKA. 
I am scoring the total energy deposited by ionizing particles on the silicon sensor layer and storing the hits in a text file in the following manner
Primary number (neutron) | Xpos of the pixel | Ypos of the pixel | Energy deposited in the pixel |
For eg.
(157, 95, 131, 0.11980814999999995)
(164, 95, 125, 0.11980814999999995)
(207, 95, 130, 0.11980814999999995)
(531, 95, 124, 0.11980814999999995)
Then I plot the intrinsic detection efficiency defined as: (total number of pixel excited above a threshold to the total number of primaries registered) *100
I observe that the detection efficiency seems be increasing upto a point and then falling down while ideally it should be increasing linearly before plateauing (image attached).
Could somebody please help?

Question

I need to gather the diminishing wave graphs of water ripples (height over time), as caused by a water droplet or other central disturbance, in a circular tank of water.  The points I'd measure would be along an arbitrary line that originates at the center and goes to an edge of the tank (because I'm assuming the central disturbance will generate circularly symmetric waves).  How could I gather the data necessary to generate the diminishing wave graphs at each point?  Using bobbers/floats and aiming a high-speed camera perpendicular to the water's surface with a grade scale behind the clear tank won't work because the bobbers/floats likely would move freely around in the tank and not stay still.  I only want them to move up and down--to measure the height of the surface of the water as it ripples.  Would multiple lasers be able to detect the water's height?
Alternatively, if there is a (preferably free) software that can simulate simple ripples and generate the needed data, I would gladly be open to that route.
Any help on this issue would be greatly appreciated! Thank you.

Answer
Definitely a good idea, Michael; I was hoping that I could get away with using a single line laser, so I wouldn't have to invest in multiple lasers.  And yeah, if I could find an accurate simulator that I could pull data from, I would definitely love that approach (would save a lot of time and labor)

Do you know any a high magnification MACRO/MICRO LENSES designed for large format sensors such as Full-frame or APS-C, which is used for observation of my experiments. I am searching the lenses with optical magnification larger than 20X and long working distance (>3 cm).
Less than 5 µm object should be seen by using combination of the lens and a DSLR camera.
One candidate was found as shown by the attached link. Its maximum magnification is 16X. I am expecting to find a better one. Pls tell me if you know any better solutions.
Thanks a lot.
Relevant answer
Answer
How important is working distance? 
The Infiniprobe TS-160 achieves 16x magnification at 18 mm working distance.  At 28 mm working distance, magnification is only 4x.
Have you considered using a long working distance microscope objective - either with a suitable tube lens, or projecting directly onto the camera sensor.
The Olympus SLMPN 20x has a shorter (25 mm) working distance, but appears to be specified for a larger image circle (26.5 mm).
There could be some loss of resolution without a tube lens, but you should have no problems imaging objects less than 5 microns.  If there is significant performance drop-off in the corners of an APS-C or FF sensor, you could use a 1.4x or 2x teleconverter on your DSLR, but this may not be necessary.

For monitoring tool or work piece we use sensors to measure many parameters(Thrust Force, Torque, Acoustic Emission etc) during machining operation.

Relevant answer
Answer
Dear Dibyanshu,
Monitoring systems heath using vibrations has been already done (for electric machines monitoring). In this context, you may have some information about the vibration signal features (frequency and so on) about the monitored items (in your case hole quality). A first step should be to characterize the the hole quality regarding the vibration signal. Afterwards, you may proceed with the on-line monitoring.
We dealt with monitoring issues using electrical measurements but the monitoring approach is almost the same. In this context, you can have a look on my tutorial posted in researchgate (see the given weblnk).
