“As electronics devices become increasingly powerful and smaller, powering these devices has become a significant concern. It may be troublesome to find compatible power sources when a user is frequently mobile and devices often require multiple recharges per day.” There’s now a new energy-harvesting solution to the problem – the chew-powered fake-tooth piezoelectric generator. It’s […]
