Soft shoe shuffle – smart shoe devices generate walking power…

Power Generation:

The devices represent a trade-off between power generating capacity, size and other factors

German researchers have built shoe-sized devices that harvest power from the act of walking.

The technology could be used to power wearable electronic sensors without the need for batteries.

There are two separate devices: a “shock harvester” that generates power when the heel strikes the ground and a “swing harvester” that produces power when the foot is swinging.

They could also form the basis of a self-lacing shoe for the elderly.

Details of the advance are outlined in the journal Smart Materials and Structures.

“We have tried to power a wireless transmitter and to power a simple sensor,” said Klevis Ylli from HSG-IMIT, a research centre in Villingen-Schwenningen, Germany.

“One application we are working on is indoor navigation which means we have sensors within the shoe that measure the acceleration of the foot, the angular velocity – whether you’re turning the foot or not – and the magnetic field.
