Abstract

Results on a designed piezo resistive transducer (PZR) are presented in this work. The PZR will be specially manufactured for accurately measuring human blood pressure levels. Such transducer consists of four indifussed piezoresistors within a 10-μm Si membrane. The voltage signal response (VSR) is predicted when pressure is applied to the membrane, using a MEMS design tool that includes Finite Element Analysis (FEA). This transducer has the purpose of serving as a basis for the integration of an implantable Bio-MEMS BP sensor.
