Abstract:
1. An ambient energy harvesting system comprising: a magnetic flux-generating assembly; a coil positioned adjacent to the magnetic flux-generating assembly; and a cantilevered arm, wherein vibration of the cantilevered arm enables relative movement between the magnetic flux-generating assembly and the coil to generate an electric current in the coil; a stabilizer positioned for linear adjustment along the cantilevered support; an actuator for selectively adjusting the stabilizer relative to the cantilevered arm to adjust an effective flexible length of the cantilevered arm; and a controller assembly operatively connected to the actuator for adjusting the effective flexible length of the cantilevered arm such that applied kinetic energy causes the cantilevered arm to vibrate at approximately its resonant frequency.
