Title: A Multi-terminal Pressure Sensor With Enhanced Sensitivity
Author: Coraucci G.O.

Abstract: This paper describes the design, microfabrication and characterization of a CMOS compatible Multi-Terminal Pressure Sensor (MTPS). This sensor is an alternative to the pressure sensors based on the conventional silicon Wheatstone piezoresistive bridge (WB) or four-terminal piezotransducers. The layout of the MTPS is designed in such a way that the sensor sensitivity is effectively improved and the short-circuit effects, which are modeled by the Geometrical Correction Factor (G), can be minimized. The sensor design was supported by Finite Element Method (FEM). The MTPS sensitivity amounts to 4,8 mV/psi. ©2009 IEEE.
