Wireless Batteryless Remote Sensors for Automated Monitoring, Control, and Inspection, Phase I

Completed Technology Project

Project Introduction

Wireless Batteryless Remote Sensors for Automated Monitoring, Control, and Inspection, Phase I
Two new catogories of wireless batteryless sensors are proposed: magnetoelastic and LC type. These sensors are also chipless which provide significantly lower cost and also higher operating temperatures than chip-based sensors. This technology is al alternative to SAW (surface acoustic wave) wireless sensors that cannot operate through many materials layers, such as in a vehicle structure or fuel tank. Magnetoelastic sensors and LC sensors operate at lower frequencies that have better penetration and also enable lower-cost readers and antenna arrays to be constructed. Among the parameters that can be sensed are: temperature, pressure/strain, humidity, and chemical enviroment. The PI is the inventor on several patents (others pending) for these sensor technologies.
