- Abstract
- The effective piezoelectric material area was determined by comparing data for different lengths of piezoelectric material on a substrate plate for a hitting-type piezoelectric module. Experimental results show that longer piezoelectric material lengths enable higher output power per unit volume. Further, as the piezoelectric material length increases, the maximum output power frequency increases and the matching impedance, or resistive load, decreases. In modeling the piezoelectric modules (cantilever beam), a UV resin coating was used to enhance the output power per unit volume in a hitting-type piezoelectric energy harvesting system. Comparison results of with UV and without UV coating showed that as the piezoelectric material length increases, UV coating has a greater effect on increasing the output power.
