Wireless SAW Sensor Strain Gauge & Integrated Interrogator Design, Phase I

Completed Technology Project

Project Introduction

Wireless SAW Sensor Strain Gauge & Integrated Interrogator Design, Phase I
Wireless, passive, Surface Acoustic Wave (SAW) temperature sensors, which can operate in a multi-sensor environment, have recently been successfully demonstrated. A network of four (4) Orthogonal Frequency Coded (OFC) sensors developed at the University of Central Florida (UCF) has been successfully interrogated wirelessly at a distance of seven (7) feet with a transceiver system developed by Mnemonics, Inc (MNI). A single temperature sensor has been interrogated at a distance of twenty-one (21) feet. This proposal extends that work in two (2) important areas. The first is in the development of an additional sensor type, a strain gauge. The second is in the design of an integrated interrogator system. These will be useful devices for a broad range of NASA, as well as commercial applications. More »
