Abstract
A sensor may include a base, a resonator centered over the base, and an accelerometer disposed in a base of the resonator. The resonator may be configured to harvest energy from vibratory motion of a host device and includes a slot disposed on a center rectangular plane of the sensor. The sensor may include a circuit arrangement disposed on the accelerometer and in the slot on the center rectangular plane of the sensor. A piezoelectric element may be mounted on the resonator and electrically coupled with the circuit arrangement. The piezoelectric element may be configured to convert vibratory energy of the resonator to electrical energy. An optional antenna may be coupled with the circuit arrangement and configured to wirelessly transmit data from the sensor to a receiving station.
