We are actively working on one of the most import and revolutionary issues of the day: energy harvesting. This is the ability to generate energy from motion or friction so that sensors can work ‘forever’. Without the need to change batteries sensors can be built into physical products such as tyres without having to worry about maintenance. Here we are using the piezoelectric properties of different materials to generate power from the flexing of the tyre wall as it compresses on contact with the road.

The advantages of energy harvesting are clear

Sensors can be fixed to the interior wall of a tyre during manufacture
No need to worry about changing batteries
Reduced maintenance time and cost
Lower total operational costs
