On contact generator 2, contact generator 2 includes: the first flexible substrates 21,21 lower surface of the first flexible substrates successively layer
The electric grade layer 22 of the first of folded setting and the first frictional layer 23 and the second flexible substrates 24,24 upper surface of the second flexible substrates according to
The secondary the second electrode lay 25 being stacked and the second frictional layer 26 and undulating electrodes layer 27, wherein undaform electrode layer 27
Support is between the first frictional layer 23 and the second frictional layer 26;The first flexible substrates 21 and/or the second flexible substrates are impacted in water wave
24 act on lower undulating electrodes 27, and deformation occurs makes the first frictional layer 23 and/or the second frictional layer 26 and 27 phase of undulating electrodes layer

Two kinds of materials of layer 23 or the second frictional layer 26 and undulating electrodes layer 27 contact with each other and electric charge transfer occur on the contact surface.
After ripples are decorporated, due to the restoring force of the elasticity of 27 material of undulating electrodes layer itself, separated between two kinds of materials, and
Opposite polarity contact charge is formed on each face.Since positively charged contact charge and electronegative contact charge are
The potential generated on one electrode layer 22 or the second electrode lay 25 and undulating electrodes layer 27 has differences, in order to balance the potential
Difference, to form the pulse current for passing through signal generating unit 3.When water wave external force applies again, due to the first frictional layer 23 or
