Dyson Energy Bracelet
The Dyson Energy Bracelet, created it Mathieu Servais, Camille Lefer, Clement Faydi, and Mickael Denie, converts the temperature difference between the skin’s surface and the ambient air to produce electricity that is then stored in a battery. The Seebeck effect is the thermoelectric effect that occurs in this process.
The bracelet comes with a micro-USB port, so that small devices such as cell phones and mp3 players can be charged from the electricity produced by the individual. In this proposal, the bracelet only provides a small burst of electricity that can provide extra minutes on a device, but not a complete charge.
