Abstract
The present invention related to a new passive wireless sensor platform which is based on the intermodulation communication principle. The platform may utilize a quartz crystal or other mechanical resonator. Additionally, the platform allows for a narrow bandwidth and/or ID-code of a sensor. Certain embodiments enable high frequencies and large read-out distances. It facilitates a generic sensor element and can thus be used to monitor virtually any quantity. Additionally, it offers a means to realize a wireless passive sensor using MEMS sensor technology.
