Multifunctional Biface Sensor Tag In article number 2200027, Lukas Rauter and co‐workers show that the fastest‐growing waste stream in the world is electronic waste. The number of sensors deployed increases rapidly, which raises the urgent demand for sustainable sensor solutions. Addressing this challenge, Silicon Austria Labs present a Multifuncti...
Requirements for the miniaturization of electronics are constantly increasing as more and more functions are aimed to be integrated into a single device. At the same time, there are strong demands for low‐cost manufacturing, environmental compatibility, rapid prototyping, and small‐scale productions due to fierce competition, policies, rapid techni...
In this article, a sustainable, multifunctional, low‐cost, wireless sensor tag is presented. The sensor tag combines three different environmental sensors in one single platform for the dedicated purpose of wireless structural health monitoring of a variety of applications. However, the adaptive design allows the integration of different sensors de...
Humidity is one of the most relevant physical parameters to sense and control for a wide range of commercial and industrial applications. Consequently, there is continuing demand for the development of innovative and sustainable humidity sensor solutions. Here, the development and characterization of fully additively manufactured, highly sensitive,...
Renewable energy sources such as photovoltaic (PV) technologies are considered to be key drivers towards climate neutrality. Thin-film PVs, and particularly copper indium gallium selenide (CIGS) technologies, will play a crucial role in the turnaround in energy policy due to their high efficiencies, high product flexibility, light weight, easy inst...
In a unique approach to develop a “green” solution for in-situ monitoring, low-cost inkjet-printed temperature sensors on paper substrate were fully integrated into natural fiber-reinforced lightweight components for which structural health monitoring is becoming increasingly important. The results showed that the sensors remained functional after...
Copper Indium Gallium Selenide (CIGS) thin-film solar cells are a promising technology, but inline quality inspection systems are required for efficient high-volume production. Tests with two candidate methods: Raman spectroscopy and photo-luminescence imaging, are reported in this paper. The methods were used to estimate material compositions of C...
Printing technologies are a convenient enabler for the rapid and cost-efficient prototyping as well as for the manufacturing of flexible sensors, which can be integrated in different types of materials and wearables. At the same time printing is considered to have a low environmental impact, provided that sustainable materials are used.
As part of...
The sensitivity of three different screen-printed highly stretchable liquid metal (Galinstan) sensors towards temperature and humidity as well as their electrical behavior under compressive load were studied. The sensors’ resistances show quasi linear dependence on changes in temperature without any hysteresis. Depending on the individual sensor de...
Thin film solar cells and in particular Copper Indium Gallium Selenide (CIGS) cells have become increasingly relevant for the renewable energy market due to their high efficiencies, easy installation, high product flexibility, light weight and less labour intensiveness when compared to silicon solar cells. As for today, there are still challenges r...
Different conductive bonding strategies for the hybrid integration of flexible, inkjet-printed electronics are investigated. The focus of the present work lies on providing a practical guide comprising standard techniques that are inexpensive, easily implementable and frequently used. A sample set consisting of identical conductive test structures...
Fan-out wafer-level packaging (FOWLP) is an interesting platform for Microelectromechanical systems (MEMS) sensor packaging. Employing FOWLP for MEMS sensor packaging has some unique challenges, while some originate merely from the fabrication of redistribution layers (RDL). For instance, it is crucial to protect the delicate structures and fragile...
With the growing significance of printed sensors on the electronics market, new demands on quality and reproducibility have arisen. While most printing processes on standard substrates (e.g., Polyethylene terephthalate (PET)) are well-defined, the printing on substrates with rather porous, fibrous and rough surfaces (e.g., uncoated paper) contains...
Resistive temperature sensors on two different commercially available uncoated paper substrates have been manufactured using inkjet printing of silver nanoparticles. Their dedication is to be integrated in lightweight materials made from natural fibre-reinforced biopolymers for condition monitoring during the manufacturing process and beyond. The p...
A method to combine additively manufactured substrates or foils and multilayer inkjet printing for the fabrication of sensor devices is presented. First, three substrates (acrylate, ceramics, and copper) are prepared. To determine the resulting material properties of these substrates, profilometer, contact angle, scanning electron microscope (SEM),...
A screen printed pH sensor was developed using a PANI layer as a proton sensitive material for the in-situ measurements of matrix cross-linking. The sensor showed a linear response in a broad pH range (3–10) and had an evident cross-talk to Cl− ions. Preliminary in-situ measurements showed a substantial signal change during the cross-linking proces...
Microclimatic conditions inside of the enclosures of photovoltaic (PV) inverters are suspected to have a tremendous impact on degradation and failure modes of the devices. To address this issue, a custom multi-channel data logger has been designed which is capable of continuously measuring temperature, relative humidity and wetness in confined spac...
Questions
Question (1)
I am looking for companies that commercially provide reverse offset printing machines for PE in research and industry, but I can't find anything on Google. Are all of the systems reported in literature self-made or are there companies who at least provide consulting for the setup of such printers?
Thank you,
Kind regards,
Johanna

OledSolar aims to tackle these challenges by developing innovative manufacturing processes for critical steps in the production of opto-electronic devices, including OLEDs, OPVs (organic photovoltaics) and CIGS (copper indium gallium selenide) solar cells. Related project activities include scaling up reconfigurable high-yield processes, testing them in pilot lines and validating them in production lines.
A complete system of inspection, quality control, functional testing and measurements using advanced systems and sensors will be optimised in the project for efficient manufacturing of opto-electronics parts. A special focus here is on automation and advance data processing for the overall control and monitoring of roll-to-roll (R2R) and sheet-to-sheet (S2S) manufacturing processes. At the same time, recycling and re-use strategies will be developed to ensure resource efficiency and reduction of high-value product waste.
The research focus is on pioneering lightweight developments with integrated sensors and efficient process analysis. The “Smarter Lightweight Construction 4.0” project bundles the competencies of three research institutions in Carinthia and at the same time represents a link to the cross-cutting issue of Industry 4.0.
