| Abstract Scope |
Pressure sensors are essential across a wide range of applications, including robotics, industrial monitoring, and wearable health systems. In particular, self-powered sensing architectures are highly advantageous for remote and distributed systems. In this work, I present a triboelectric-based sensing approach that generates an open-circuit voltage directly from applied pressure, enabling a self-powered transduction mechanism. I will outline the physical principles that allow the sensor to detect both strain and strain-rate, enabling us to decouple the pressure magnitude from its temporal profile. Additionally, I will describe how additive manufacturing, specifically aerosol jet printing, can be used to enhance device performance. By texturing the sensor electrodes and deformable elastomer layer at the microscale, we achieve a fivefold increase in overall sensitivity. |
