"MicroBelt or MicroWindbelt": World’s First ‘Peel & Stick’ Wind Harvester Created by Humdinger Wind Energy

Humdinger Wind Energy LLC seriously believes that the scaled down versions of wind turbines could power tiny wireless sensors to bring about the new information age. It has developed a device called the MicroBelt to replace the use of batteries for powering these sensors. The device utilizes aeroelastic flutter and membranous vibration and does not feature a spinning turbine. Hence, even at a minimal wind speed, say 3 m/s, the device can produce milliwatts of power with ten times more efficiency. At 5.5 m /s of wind flow, the power output is 2mW.

The MicroWindbelt can continuously provide power to any application where air is flowing: under a vehicle, inside the ducting of a building, or at the out-flow of a factory. So very soon, you might see this cell phone-sized wind-generating device finding applications in building monitoring and transit monitoring. The wireless and battery-free device is made from relatively cheaper materials and is perfectly portable.
