Abstract
An apparatus and method for generating electricity using piezoelectric material. The apparatus comprises a first elongate member and a second elongate member that are joining together at first and second points which are spaced apart from each other. The second elongate member comprises a piezoelectric element, or has a piezoelectric element mounted thereon. When pressure is applied to the first elongate member, the second elongate member is stretched and the stretching force is applied to the piezoelectric element. This generates electricity. A similar arrangement with a third elongate member may be provided on the other side of the second elongate member. The apparatus may be placed in a shoe or underneath a floor, so that the variation in pressure caused by walking may be used in generate electricity.
