Abstract
A device for generating electrical energy has a sheet of piezo material with an array of holes formed therein. At least some of the holes are filled with ferro fluid which expands in the holes upon being subjected to a change in magnetic energy. The sheet of piezo material generates an electrical potential in response to applied mechanical strain caused by the expansion of the ferro fluid in the holes of the piezo sheet.
