VIBRATION-BASED ENERGY HARVESTER WITH STRAIN OPTIMISED TOPOLOGY |
摘要 |
An apparatus is provided for harvesting energy from mechanical vibrations with an improved power output. The apparatus comprises a frame (22), a first member (20) comprising a piezoelectric material, a cantilever beam (26) and an electrode. The first member is fixed to the frame at a first position and a second position and extends between the first and second positions. The cantilever beam has a first end fixed to the first member between the first position and the second position and a second end fixed to a proof mass (24). The electrode is fixed to the first member at a position between the first position and the second position. In another aspect, the apparatus may comprise a plurality of proof masses connected to the first member between the first and second positions in a spaced relationship to one another. |
