In this paper, a novel design of a fingerprint sensor composed of a 2D array of piezo resistive micro beams has been presented. When the user presses the sensor array with a finger, the ridges and valleys that compose the fingerprint induce corresponding deflections in the micro beams. These deflections can be detected by means of a resistivity change, which when used with appropriate signal ...

PEM fuel cells are very promising for portable applications. A key component of fuel cell is the flow field plate through which hydrogen will reach the anode, oxygen will reach the cathode and electron collection. Flow field plate made of silicon is not a good electrical conductor , so electrical contacts has to be attached to the Gas Diffusion Layer (GDL) for taking the power to outside ...

MEMS gyroscope technology provides cost- effective method for improving directional estimation and overall accuracy in the navigation systems. This paper presents a tuning- fork gyroscope (TFG)  with a perforated proof mass. The perforated proof mass used in the design enables the reduction of the damping effect. This MEMS based gyroscope was designed using COMSOL Multiphysics 4.2a. This ...
