| Abstract: A novel measurement technique is employed using surface acoustic wave
(SAW) devices, passive RF, and radiation-sensitive films to provide a
wireless passive radiation sensor that requires no batteries, outside
wiring, or regular maintenance. The sensor is small (<1 cm.sup.2),
physically robust, and will operate unattended for decades. In addition,
the sensor can be insensitive to measurement position and read distance
due to a novel self-referencing technique eliminating the need to measure
absolute responses that are dependent on RF transmitter location and
power. |
