The Dyson Energy Bracelet is a gadget that uses Seebeck effect to harness energy and power your mobile phone for a few precious minutes more, when you desperately need it. In case you slept through your advanced science class, the Seebeck effect involves thermoelectrics, and in this case, the direct conversion of temperature differences to electric voltage. Essentially, the temperature difference between the surface of the energy bracelet that’s touching the skin, and the other which is exposed to ambient air, produce electricity that is stored in a battery. When the wearer needs to recharge a mobile device, they simply plugs it into the Dyson Energy Bracelet through a micro-USB port.
