dc.description.abstract |
The concept of harvesting energy in the ambient
environment arouses great interest because of the
demand for wireless sensing devices and low-power
electronics without external power supply.
Harvesting energy by vibration with piezoelectric
materials can be used to convert mechanical energy
into electrical energy that can be stored and used to
power other devices. This conversion of vibrations
(mechanical energy) to electrical energy using
piezoelectric materials is an exciting and rapidly
developing area of research with a widening range
of applications constantly materialising. In this context,
the goal of this paper is to develop a comprehensive
prototype generator that can harvest vibration
energy and convert it to electrical energy by
providing the output power for optimisation and its
performance. Two setups of prototype are used: a
cantilever beam with tip mass at the end, and a cantilever
beam without tip mass at the end. Data from
the experiment is compared and analysed using
MatLab. The results show that the power output of
the prototype with the tip mass is greater than the power output without the tip mass. The experimental
results led to a power optimisation from that prototype
by different characteristic of piezoelectric
ceramic plate. |
