The paper presents a piezoresistive absolute micro-pressure sensor for altimetry. This investigation includes the design, fabrication and testing of the sensor. An improved structure is studied through incorporating sensitive beams into the bossed-diaphragm structure. By analyzing the stress distribution of sensitive elements using finite element method (FEM), the configuration shows an enhanced sensitivity...
Presented is a piezoresistive absolute micro-pressure sensor, which features relatively high sensitivity and overload resistance simultaneously. In this investigation, the design, fabrication and testing of the sensor are carried out. By analyzing the stress distribution on sensitive elements using the finite-element method (FEM), an improved structure through introduction of sensitive beams and islands...
A kind of micro piezoresistive pressure sensor with stable performances under high temperature is designed based on the silicon on insulator (SOI). Through analyzing the stress distribution of diaphragm by finite element method (FEM), the model of structure was established. The fabrication operated on SOI wafer, which can be used in extreme high temperature environments, and applied the technology...
