PIEZOELECTRIC POWER GENERATION |
摘要 |
Technologies are generally described for generating electrical power from piezoelectric power. Example devices/systems described herein may use one or more of a piezoelectric device, a plurality of solid particles, and/or a container. In various examples, an electrical power generator apparatus is described, where the apparatus may be configured to provide an electrical signal upon application of a mechanical stress to the piezoelectric device. Some example apparatus may also be configured to contain the plurality of solid particles in the container, which may be coupled to at least a portion of a surface of the piezoelectric device. When a mechanical force is exerted on the plurality of solid particles, the plurality of solid particles may be effective to receive at least a portion of the mechanical force and responsively apply the mechanical stress to the piezoelectric device. |

1. An electrical power generator comprising:
a piezoelectric device configured to provide an electrical signal upon application of a mechanical stress to the piezoelectric device; a plurality of solid particles; and a container coupled to at least a portion of a surface of the piezoelectric device, wherein the container is configured to contain the plurality of solid particles, wherein, when a mechanical force is exerted on the plurality of solid particles, the plurality of solid particles are effective to receive at least a portion of the mechanical force and responsively apply the mechanical stress to the piezoelectric device. |
