In order to study on output voltage of flexible piezoelectric power generation assembly excited by waves

based on numerical wave flume

the two-way coupling analysis of different styles of flexible piezoelectric energy harvester and waves

such as tandem placement at different distances

unimorph

bimorph series

and bimorph parallel are carried out. The results shows the harvester can output a stable voltage under the action of waves; the swing period of the piezoelectric sheet is the same as the period of the wave

and the swing phase difference between the two piezoelectric sheets is related to the distance between the piezoelectric sheets arranged in series. Under the selected wave conditions

the output voltage is the largest when the distance is 400 mm; the voltage of the unimorph and bimorph parallel is basically the same as half of the bimorph series; regardless of unimorph or bimorph

parallel or series

the maximum output voltage of the piezoelectric power generation assembly is obtained when the length is 125 mm.
