Abstract

This paper presents the design and simulation of blood pressure sensor for healthcare and biomedical applications. Generally blood pressure can be measured by using sensors externally, but here is an implantable sensor which is used for continuous monitoring of blood pressure. The software used is COMSOL Multiphysics, a general purpose software platform for modelling and simulating the advanced applications. This work describes the design of nanotube-based sensor with a basic known technology of MEMS. The main physics used in this design is solid mechanics and time-dependent analysis which is performed to certain values of pressure that is applied on the model. The pressure versus displacement analysis is performed, and it is observed that the pressure is directly proportional to displacement. The device performance is compared by using materials like Si and Au. The result shows that Au has good sensitivity than Si which is verified by calibration method.
