Abstract
One of the factors limiting performance of PZT material in energy harvesting applications is its tensile strength, which limits its maximum allowable strain. In typical cantilever beam harvester the piezoelectric patch placed on the beam is periodically stretched and compressed during vibrations. Exceeding specific value of tensile stress leads to damage of piezoelectric material and impairment of its energy conversion capabilities. One of the distinct properties of all ceramics, also PZT, is exhibiting low strength in tension but, simultaneously, very high compressive strength. Aim of this work was to introduce initial compressive stress into piezoelectric layer, therefore increasing allowable beam deflection during vibration. To determine effect of piezoelectric patch prestressing on harvester performance a series of numerical simulations were done.
