Abstract
A zero power radio frequency (RF) activated wake up device is provided. The device is based on a high-Q MEMS demodulator that filters an amplitude-modulated RF tone of interest from the entire spectrum while producing a much higher voltage signal suitable to trigger a high-Q MEMS resonant switch tuned to the modulation frequency of the RF tone.
