Abstract:
|
The reduced power requirements of miniaturized electronics offers the opportunity to create devices having their power supply based on
energy harvesters. In this paper a new idea is proposed and studied to supply underwater low-consumption devices using low-cost disk
piezoelectric elements. The system scavenges
energy from water motion induced in depth by
surface gravity waves using piezoelectric materials
and the characteristic oscillating movement of
bodies with positive buoyancy that are attached to
the seabed with flexible cords, similar to an
inverted pendulum. The piezoelectric components
that are subjected to impacts produced by the
movement of the pendulum create an electrical
power generator that harvests the mechanical
energy brought by the sea movements. A prototype
with the proposed electronic harvesting system is
built and tested. The average power output of the
prototype is 2.2 ± 0.3 µW, which can be increased
signi¿cantly with further optimization. |
