Modeling and Testing of Eco-friendly Piezoelectret Sensor for Anthropocentric Pressure Measurements
The ability to measure vibrations is a vital engineering problem. From measuring pulse for health diagnostics to sensing pressure on a touch screen for a smart phone, the applications vary far and wide. In our group we study the use of polymer-based devices called piezoelectrets to measure pressure signals for a variety of applications. Our microfabricated polymer approach yields superior flexibility, piezoelectric coefficients, and costeffectiveness when compared to traditional ceramic material competitors. The devices themselves also vary in material composition and geometry depending on the application. In this project we explore the potential of using environmentally friendly materials for the fabrication of a piezoelectret pressure sensor without compromising performance.
