Piezoresistive pressure sensor with high sensitivity for medical application using peninsula-island structure

         

摘要

A novel micro-electromechanical systems piezoresistive pressure sensor with a diagonally positioned peninsula-island structure has high sensitivity for ultralow-pressure measurement.The pressure sensor was designed with a working range of 0-500 Pa and had a high sensitivity of 0.06 mV·V-1·Pa-1.The trade-off between high sensitivity and linearity was alleviated.Moreover,the influence of the installation angle on the sensing chip output was analyzed,and an application experiment of the sensor was conducted using the built pipettor test platform.Findings indicated that the proposed pressure sensor had sufficient resolution ability and accuracy to detect the pressure variation in the pipettor chamber.Therefore,the proposed pressure sensor has strong potential for medical equipment application.
