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.

Message to Sponsor

I would like to thank the Johnson Fund for making it possible for me to participate in the SURF-SMART Program. This experience has been monumental in helping me decide to apply for graduate school upon completion of my bachelors degree. With making this decision, I realize that as a latina woman in engineering, there are many more bumps and detours that lie ahead. This project, which I plan to continue working on during the fall semester, has helped me realize that I am not alone in my new endeavor, and that I have people who are willing to take a chance on me. I have gained considerable knowledge and skills pertaining to my research and beyond. I have much more confidence in my work and myself. I will forever be grateful to the opportunity given to me. Once again, thank you.
