DEVELOPMENT OF PIEZOELECTRIC CERAMIC HAVING EXCELLENT ENERGY TRANSFORMATION AND STORAGE EFFICIENCY

摘要

Purpose: the development of the piezoelectric ceramics with the conversion of good energy and storage efficiency is arranged to the conversion loss energy since vibration and impact enter available energy. Construction: a device is provided with a pair of of piezoelectric ceramics spares provisioning, it is with pressure, vibration, and impact, an electrode (22), a metal portion (24) and a conductive film, the wherein both sides of each and piezoelectric ceramic part, a structure, it, which is used to enter one by dividing electrode, makes that energy conversion efficiency reaches maximum or multiple units, a Burton's line are connected, it is used for transmission piezoelectric ceramics, shell is transmitted in one pulse, and one complicated piezoelectric structure and material (40) pulse, including organic/inorganic builder material and a kind of polymer adhesive.
