During speed of 2 to 6.5 km per hour, the researchers were able to achieve a capacity of 1.6 microwatt. Is the speed of normal walking. This energy can accumulate and then charge portable electronics, such as smartphone.
While the development is under testing. However, in the future, developers want to produce mass product, which could become an alternative to portable batteries, because to charge the gadget, it is necessary to walk a bit.
