The invention is a microminiature wireless environmental sensor that has
integrated both sensor and transmitter functions into one function. The
basic operating principle for the device is that variable components of
an RF circuit can be interfaced to the outside world environmental
signals resulting in proportional changes in the transmission
characteristics or transmission of data/bits from the RF transmitter
circuit. This utilization of environmentally sensitive variable elements
within a wireless transceiver circuit permits the fusion of both sensor
and communications function into an integrated single function.
