In the last few years,
there has been an increasing demand for low-power and portable-energy sources
due to the development and mass consumption of portable electronic devices.
Also, the portable-energy sources must be associated with
environmental issues and imposed regulations. In this context, piezoelectric materials are becoming
a better alternative for energy generation
and storage in future applications. In
locations where traditional power sources may not be available and long periods
of unattended operation are required, the power may become inadequate. In such
cases, some source of vibrating energy may be
present in operation of the machine.

A piezoelectric source
is used to generate power for the operation of a microcontroller and radio
transmitter. Also, the use of piezoelectric polymers
in order to harvest energy from people walking and the
fabrication of a shoe capable of generating and accumulating the energy is a new
trend. It can be used in wearable
healthcare applications where the healthcare device can harvest its needed power, and sense vital
signs from the human body. Ecological security is an important issue in
the current scenario. Pollution and ecosystem degradation is often encountered
with many energy sources. The method of generating eco-friendly electricity
using piezoelectric material helps reducing global warming. The model with piezo material converts the scavenged
mechanical energy-vibration
and rotation to electrical energy for
powering the various electric devices. This allows the material to function as
a power harvesting medium. The significance of the
proposed approach results in generation of electricity in hilly areas using
natural resources and in rural areas through tube-well water pressure.
