Wristify promises personal heating to cut fuel bills
Copper Wristfy bracelet warms skin directly, reducing the need to heat buildings
A high-tech copper bracelet could soon regulate your body temperature without the need for heating or air conditioning, scientists have predicted.
Wristify, developed by a team at MIT, could substantially cut energy consumption and fuel bills by reducing the need to heat or cool buildings.
Described by the Independent as a thermoelectric bracelet, Wristify works by monitoring body temperature and sending “tailored pulses of hot or cold waveforms” to the wrist through a copper-alloy heat sink.
“The human body and human skin is not like a thermometer,” said Sam Shames, an engineering student at MIT, who helped to design the device. “If I put something cold directly on your body at a constant temperature, the body acclimates and no longer perceives it as cold.”
Wristify makes use of that response to trick the body into thinking it’s either hot or cold. Even in a cold room, the wearer of the wristband would feel warmer throughout his or her body.
“This is why a cool flannel applied to forehead of a flu sufferer can help them feel more comfortable,” the Independent reports.
The prototype recently won the $10,000 first prize in MIT’s annual materials science and engineering competition. The team said they would use the money to continue the development of the prototype in the hope of making it commercially viable. ·
