Abstract

The present study describes the MEMS-based piezoelectric switch to activate the event-driven wireless sensor node for chicken health monitoring system. We have fabricated the switch composed of “S” shaped piezoelectric cantilever and proof mass, where the resonance is 24 Hz. When the switch has been vibrated at 4, 6, 8, and 12 Hz, which is close to the chicken movement frequency, the input vibration was converted into the resonant one through superharmonic resonance leading to enough voltage to activate event-driven operation.
