| 20100045111 | MULTI-LAYER MODULAR ENERGY HARVESTING APPARATUS, SYSTEM AND METHOD - A multilayer piezoelectric generator is disclosed comprising a round, rectangular or other shaped box having a cover. In the box are top and bottom electrodes and a plurality of electricity generating layers. Each Layer comprises a plurality of piezoelectric rods held in place by a matrix layer that fits snugly in the box and configured to accept shear strains developed in the rods when pressure is applied to the cover. The layers are separated by central electrode layers. The structure is configures such that pressure is evenly spreads among all the rods and causes the rods to make contacts with the electrodes. Rods in adjacent layers are oppositely poled, and the electrodes are configured and wired such that all the rods are connected parallel such that their generated charge is summed. Adaptation of the generator to its application is done by changing the number and thickness of the layers. | 02-25-2010 |
