Pavegen tiles are floor tiles that convert kinetic energy from footsteps into electricity. They contain piezoelectric generators that produce small amounts of electricity when people walk on them. This captured energy can be stored and used to power small electronics. The tiles have been installed in locations with high foot traffic like schools, offices, and transit stations to demonstrate their ability to generate renewable energy from human movement. The presentation provides details on how the tiles work, their applications, installations, energy outputs, and advantages as a renewable and eco-friendly energy source.

PAVEGEN
• Most of the countries try to innovate
alternative electricity power for their usage.
• In civil construction field, we are introducing
a energy conserving technology as a
replacement for tiles.
• Laurence Kembell-Cook, the director of
PaveGen Systems imagined a new idea to
generate electricity from pavement slabs.

• The idea later named as Pavegen
technology.
• It is also known as Kinetic footfall.
PAVEGEN TILES
• Pavegen is a technology
that has been developed by
paving slab tiles to convert
energy from people’s footsteps
into electric power.

What are Pavegen tiles?
.
Kinetic floor tiles or pavegen tiles capture
energy generated when people walk on
them.
• These floor tiles generate electricity through the
deformation of the material under a load.
• It can be stored
and used for a
variety of
applications.

• The old version of these tiles are square
shaped.
• The latest version is in the
shape of triangle which consists
of a generator in each corner
which maximizes the energy
output no matter where you step.
• The top surface of the flooring tile unit is made
from recycled rubber and stainless steel.
• The base of the slab is constructed from over
80% recycled materials with concrete.

WORKING PRINCIPLE
• Kinetic tiles work because of the scientific
principle of piezoelectricity.
• When an object is
subjected to mechanical
pressure (ie: something
steps on it) it creates an
electrical current.
• A piezoelectric element like PZT, PVDF, etc., is used
as transducer.
• It converts the kinetic energy into electrical energy
upon stepping on the floor tile.

How does it
work?
• Pavegen’s tiles are electro-magnetic.
• The tiles have flywheels beneath
them that spin when walked on,
producing up to 7W with every
footstep.
• There are generators in each corner.
• The electricity can be used to power
appliances directly, or stored for later use.

Achievements
• 20 kilowatt-hours or 72 million joules of
energy in 2 weeks.
• Received Big Idea Prize in The
Observer's annual Ethical Awards.
• Count foot steps.
• 5 watts per footstep at 12-48 volts DC.
• 4 hours on PaveGen paving would
generate 0.02% of the average
European's energy needs.

APPLICATIONS IN CIVIL
ENGINEERING
• This idea can be implemented in the
floors of crowded places as footpaths,
railway platforms etc.
• Stairs can be also used for production of
energy by mere walking.
• Used for security purposes and in
various alarm systems.
• For street lights.
• In bus station.
• In airports.
• In play grounds.

• Tiles are completely Renewable & Eco friendly
technology.
Advantages
• It is waterproof and damp proof.
• This technology is highly suitable for urban areas.
• No need fuel input.
• This is a Non-conventional system.
• Less maintenance cost.
• We can reduce approximately 6.817 tons of
excessive CO2 every day emissions by tiles into
atmosphere, by using Pavegen technology.

Disadvantages
• Low amount of energy is produced during each step
or movement of the slab.
• Initial cost is extremely high [ from $75 to $160 per
square foot ]
• Uncertainty about economic life.
• Market acceptance and most productive use.
• It cannot be used as a primary energy source.
.
• In India, we have to import these technology for
replacement of tiles.
