  ABSTRACT: This paper reports a nano-opto-mechanical pressure sensor based on nano-scaled ring resonator. The pressure is measured through the output spectrum shift which is induced via mechanical deformation of the ring resonator. The sensitivity as high as 1.47 pm/kPa has been experimentally achieved which agrees with numerical prediction. Due to the strong variation of sensitivity with different ring radius and thickness of the diaphragm, the pressure sensor can be used to form an array structure to detect the pressure distribution in highly accurate measurement with low-cost advantages. The nano-opto-mechanical pressure sensor has potential applications such as shear stress displacement detection, pressure wave detector and pressure mapping etc.

  ABSTRACT: Cell arraying with single cell per trap is demonstrated using image dielectrophoresis(DEP) and leads to a 5 by 5 single cells array. The tunable energy wells, which were induced by established patterns and image control, were used to confine NIH/3T3 cells. Image was used to help cells overcome the energy barriers. It allows the controllability to rearrange cells, including locally dislodging the excess cells and repositioning them in non-occupant traps. The viability of post-assembled cells that were identified by fluorescence staining of FDA is about 90%. The continuous temperature monitoring shows that the device used reached its thermal equilibrium of 36degC, close to the 3T3 culture temperature of 37degC.

  ABSTRACT: This study presents the nonvideo, noninvasive, automatic, and on-site monitoring system employing ultrasonic transducers to detect the behavior in sows before, during and after parturition. An ultrasonic transmitting/receiving (T/R) circuit of 40kHz is mounted above a conventional parturition bed. The T/R units use ultrasonic time-of-flight (TOP) ranging technology to measure the height of the confined sows at 8 predetermined locations. It is suggested that the system could be applied to automatic prediction of sow parturition, with automatic notification of remote management personnel so human attendance at the birth could reduce rates of sow and piglet mortality.
