Human dynamo: Movements of knee to generate power for gadgets

We love green energy, we’ll spend every single effort to find ways to generate green power for our gadgets, even though it’s little absurd. The new idea here is to make use of the movements of your knee to generate electricity to power your portable gadgets or cellphones. It’s be a device that is to be strapped to your leg around the knee, converting the movements of your knees into electricity while you’re walking.

Surely, at the early prototype stage of the device, it looks bulky, which makes you look little absurd, like a Robocop. Perhaps, it’ll make you a little bit clumsy with your movements, while having it strapped to your knee. The researchers are looking into the possibility of making a much smaller version that could be incorporated into clothing.

Dr Arthur Kuo of the University of Michigan is the inventor of this device. And he calls it “biomechanical energy harvester”. He said the device works similar the power-generating brakes found in hybrid cars.

Anyway, this device will be helpful for joggers to power up their iPods while running or commuters to charge their mobile phones while dashing for a train.

US and Canadian scientists have created a unique and useful device that will use your body movements while walking to charge up your batteries for a whole host of gadgets. As a human dynamo you will effortlessly produce enough energy to power up your mobile for 30 minutes form just one minute walking.

The dynamo is strapped to your knee and works as you move, using a process that similar to those found in hybrid cars. Each one of your steps will generate power using the car technology known as ‘regenerative braking’. The knee brace has a series of gears and sensors that are used to assist your muscles in the walking action and simultaneously produce electricity.

Your energy harvesting efforts will give off 5 watts of electricity (for a slow walk), and at 1.6kg and aesthetically-challenged this early version is not quite ready for either the rigours of daily living or the catwalk.
