Compact and portable electronics, are extremely popular. To solve the main problem of constant battery energy consumption, scientists have found a way to charge batteries literally on the move.
Clothing and accessories are made of sufficiently strong and flexible fabric that is able to generate energy when people move. This amount of energy is enough to maintain the operation of several portable electronic devices. Different types of textiles use different ways to produce energy: "solar" textiles with photocells are charged by light, piezoelectric ones convert kinetic energy, which is a result of stretching, twisting and friction during movement. Who would have thought that a backpack straps’ wiggling can be such a benefit?
