Abstract

Blood pressure detection requires both sound detection and pressure measurements. Piezoelectric materials fulfill both aims. Starting from a previous work, a pressure sensor based on a SOI transistor with a piezoelectric layer, was adapted for the blood pressure domain. The ANSYS simulations provide the mechanical stress in the structure. The ATLAS software simulates the electrical behavior. This paper offers a modeling of the sensor and consequently design guidelines.
