Abstract

An acoustic detection system and method and associated kinetic energy harvester is disclosed. The acoustic detection system comprises a vibration-generating object, a kinetic-energy harvester, and an acoustic sensor. The kinetic-energy harvester is embedded within a first location of the vibration-generation object and is configured to wirelessly transmit electrical power to the acoustic sensor, which is embedded within a second location of the vibration-generating object. The acoustic sensor is configured to receive the electrical power, detect acoustic signals, and convert the detected acoustic signals into acoustic data. The kinetic energy harvester may be an electromagnetic harvester that comprises a magnet array and a coil array comprising at least one conductive coil. By inducing a current in the at least one conductive coil through the relative motion between the magnet array and the coil array, the kinetic-energy harvester produces electrical power.
