Title:
ELECTROMAGNETIC ENERGY CONVERSION THROUGH COIL AND MAGNET ARRAYS
Document Type and Number:
WIPO Patent Application WO/2013/188215
Kind Code:
A3
Abstract:
This specification describes technologies relating to converting vibration energy to electrical energy through electromagnetic transduction. According to an aspect, an apparatus to convert kinetic energy to electricity through electromagnetic transduction can include: an array of magnets arranged in a first plane; and an array of coils arranged in a second plane with respect to the first plane to form a gap between the array of magnets and the array of coils. According to another aspect, an energy harvester can include: a two dimensional array of magnets; a two dimensional array of coils; a housing configured and arranged to limit a direction of motion of either the two dimensional array of magnets or the two dimensional array of coils; and additional magnets configured and arranged to form a suspension system for either the two dimensional array of magnets or the two dimensional array of coils in the direction of motion.
