Abstract: PURPOSE: A broadband energy harvesting apparatus is provided to expand resonance frequency band on external vibration. CONSTITUTION: A mass(10) is installed to vibrate in a multidegree of freedom. Both ends of the mass are connected to vertical bars(51,52). Piezoelectrics(41,42) are installed to vibrate with the mass by reacting the vibration of the mass. Two cantilevers(31,32) are installed in parallel with each other at the same height. Bearings(61,62) are installed in the connection part of the mass and vertical bar.

Abstract: PURPOSE: An escalator which can harvest electric energy is provided to prevent energy waste by transferring redundancy torque to a generator through various gear ratios. CONSTITUTION: In escalators able to harvest electric energy, a circulating chain(130) moves up and downs passenger. A driving part(120) runs the circulating chain. A tension gauge(110) is installed near to the circulating chain to measure tension. A controller(300) switches a transmission according to the tension inputted from a tension gauge. The transmission controls the gear ratio between the driving part and the generator.
