INTRODUCTION
Objectives:
To be able to create a contactless piezoelectric shaft modification system which will
generate power when a power generator’s shaft turns, creating an additional source of power.
This contactless piezoelectric system will utilize magnetic repulsion to generate mechanical
stress to the piezoelectric material. When the wind flows through the blades, the shaft would
rotate about the shaft axis. The permanent magnet attached to the end of the shaft is rotated.
When the magnet gets closer to the magnet, which would be attached to the tip of the
piezoelectric layer, the layer is bent downwards without any mechanic contact, since the poles
of the magnets are same. Thus, every rotation creates a vibration that would be converted to
the electrical potential on the piezoelectric layer. This proposed study would be utilizing a
contactless operation with the use of magnetic repulsion to prolong the lifespan of the
piezoelectric material. In addition, the speed of the shaft as it rotates about its axis is sufficient
to continuously generate and remove pressure from the piezoelectric transducers to generate
enough current to make a significant amount of power.
