Aidin Delnavaz tested the strap that draws power from his jaw attached to a headset.

It may not be a very aesthetic accessory, but it can be useful: a strap that fits on the chin and converts the movements of the jaw into electricity.

Thus, chewing could produce the energy necessary to charge small devices, for example, hearing aids.

That’s the brainchild of a team of engineers, who created the strap with a «smart» material that charges up with electricity when stretched.

According to Aidin Delnavaz and Jeremie Voix, from the Ecole de Technologie Supérieure from Montreal, Canada, jaw movements are good candidates for offering natural energy.
