Pavegen technology generates electricity from footfalls using piezoelectric materials. It consists of piezoelectric sensors embedded in floor tiles that convert the mechanical energy from each step into small amounts of electrical energy. The piezoelectric effect causes the generation of a voltage when mechanical pressure is applied. Pavegen tiles have been used in a variety of applications and can generate 2-5 joules of energy from each footstep. They provide an alternative to solar panels for generating small amounts of renewable energy.

➢ Unsymmetrical
electrically neutral crystal
➢ Due to applied mechanical
pressure, the structure
deforms, atoms get
pushed around, and
crystal can conduct an
electrical current

8. Piezoelectric Transducer
8
A transducer can be anything which
converts one form of energy to
another. Piezoelectric material is
one kind of transducers. We squeeze
this material or we apply force or
pressure on this material it converts
it into electric voltage and this
voltage is function of the force or
pressure applied to it. The material
which behaves in such a way is also
known as piezoelectric sensor.

In this grouping, a certain
number of cells are connected
in series and all such series are
then connected mutually in
parallel. Suppose ‘n’ cells are
connected in series and ‘m’
rows of such series groups are
connected in parallel.
Hence here we have,
n=3
m=2
