ABSTRACT:
A float on a body of water is mechanically coupled to a piezoelectric material member for causing alternate straining and destraining of the member in response to the up and down movement of the float in response to passing waves, thereby causing the member to generate electricity. The output impedance of the float is matched to the input impedance of the member for increasing the energy transfer from the float to the member.
