Abstract: An apparatus for converting wave energy into electrical energy including a float element excited at a defined frequency by the waves. A power extraction system collaborates with the float element to convert mechanical energy into electrical energy, the mechanical energy coming from the movement of the float element excited by the waves. The power extraction system takes the form of a frequency amplifier made up of at least two piezoelectric motors each composed of at least one piezoelectric post excited at a frequency higher than that of the float, and a member for activating said piezoelectric motors acting on the piezoelectric motors so as to squash said piezoelectric posts. Each piezoelectric motor has a mechanical amplification device connected to rollers and includes a) jaws able to apply mechanical stress to the posts, b) a lever acting on the jaws with a proximal end connected to said jaws and a distal end connected to a roller in contact with the member so as to activate said piezoelectric motor.

Abstract: With actuators according to prior art, it is known that, in the inactive region, which is required for contact purposes, irregularities in expansion occur. These produce cracks in the piezoelectrically inactive electrode region, which may occur at regular intervals. As a result of the irregularities in expansion, the stresses accumulate in the passively expanded regions, up to a level at which they are relieved by crack formation. It is therefore proposed according to the invention that the contact surfaces (17), and therefore the inactive regions (15) assigned to them, of one or a predetermined number of electrodes of the same polarity (11; 30 to 37; 39, 40), arranged above one another in the same direction, are arranged offset to one another by a predetermined angle (22) of the size null, opposite the contact surfaces (17), and therefore the inactive regions (15) assigned to them, of the preceding internal electrode or a predetermined number of preceding electrodes of the same alignment and the same polarity.
