Germany: These smart shoes generate POWER as you walk!

Germany, Villingen-Schwenningen
January 19, 2015 at 11:59 GMT +00:00 · Published

German researchers displayed their two types of energy harvesting shoes which generate power simply through human motion in Villingen-Schwenningen, Monday.

The first device, called the 'shock harvester,' produces power when the heel touches the ground and was developed to charge the battery of an indoor navigation system. The second device, referred to as the 'swing harvester' generates power when the foot is swinging and was developed as part of a self-lacing shoe for the elderly.

Both devices contain coils of wire and a stack of magnets and rely on the motion between magnets and coils to generate power. As the magnetic field from a moving magnet passes a coil, a voltage is induced and an electric current is generated.

The energy the devices generate ranges from one to four milliWatt (mW). Although it is not enough to charge a smartphone, which typically requires 2000 mW, it is enough to power small transmitters and sensors.
