New Invention of “Shoe Sized” Generator to Power Small Devices

It seems pretty clear now that us as humans have started using and will be using computable devices for a long time to come. From eyewear to wrist strapped mobile computers and many more. This is our way of moving into the future. But an adjacent area of research these days tackles the issue of how, exactly, to best power all these devices.

According to a recent media report, researchers in Germany have proposed a new kind of smart shoe device that generates electricity with every step you take. The proposal, from research institute HSG-IMIT.

The study proposes the use of two different kinds of “inductive energy harvesters,” each radically miniaturized to fit into the sole of a standard-sized shoe. Both elements generate power by exploiting the motion between magnets and coils. “The use of energy harvesting techniques offers a way of supplying sensor systems without the need for batteries and maintenance,” according to the research paper.

The first element, called the swing harvester, does just that and captures the swinging motion of your foot as you take a step. The second element, the shock harvester grabs up energy every time your shoe strikes the ground.

The amount of energy generated from the device is relatively small not enough to power a smartphone, say. But it might be enough to power small transmitters and sensors built into other wearables. Interestingly, the device was initially designed to provide self-lacing shoes for the elderly, but has now broken into a new field of discoveries. This small yet ingenious idea may lead to us having to never worry about finding a wall socket to charge our devices or even worry about having car chargers with us. German engineers truly think of anything and everything.
