New steps to generate power by rubber tiles

London – Pavegen Systems, a London-based technology firm, has developed rubber tiles that can converts the kinetic energy from peoples footsteps into low-voltage power.

The top surface of the tiles uses up to 100 percent recycled rubber, from old truck tires, although some base models use a 50-50 mix of virgin and recycled rubber.

Energy harvested from the tiles can be used to power local applications such as lighting, advertisement displays, wireless systems and way-finding lighting, according to the company.

Pavegen’s design converts the kinetic energy of footfall into electricity that can be stored in a battery or used to power street lighting or communications technology. When stepped on, the Pavegen surface flexes a near imperceptible 5mm, generating up to 8 watts of power over the duration of the footstep.

The off grid technology can provide a low-carbon contribution in areas of high footfall, regardless of weather.

The technology has been tested to withstand over 20 million footsteps, so the greater the footfall, the larger the number of tiles, the more power can be generated.

The tiles can also withstand extreme weather conditions and work even when submerged underwater at a depth of 1.5m.

The top sheets of Pavegen tiles can be branded to suit client's needs; allowing for adaptability and personalisation of installations.
