Paper Abstract

A wireless batteryless piezoresistive pressure sensing system was presented. The sensing system adapts RFID operation principles including a transponder and a reader. The transponder device includes an energy harvesting circuit, force sensing resistors, a resistance-to-frequency converter, and an antenna. The reader provides radio frequency power to the device remotely and measures the sensor values in terms of frequency shift simultaneously. The performance of the system was characterized form 0 to 10 psi while the corresponding modulated frequency shift by the reader was between 7.35 kHz and 8.55 kHz. A pressure sensor array was arranged to identify high pressure points dynamically for long-term usage.
