MIT students developed a wristband that can regulate the body's temperature, thereby possibly eliminating the need for central heating and cooling in the future!
Sam Shames is a MIT senior who faced a rather common problem.
His body temperature usually runs hot and his mom's usually runs cold and, between the two of them, it was not easy to decide where to set the thermostat in a room when they were both occupying the same space.
He figured there must be a way where everybody can just live in peace and be comfortable at the same time, so he did some research.
He came across scientific papers that explained that heating or cooling certain parts of the body have an effect on how cold or warm we think we are.
Suddenly he asked the right question: Why, instead of heating or cooling a space with central air conditioning, don’t we just heat or cool our own bodies?
That is how he and a team of other students started working on ‘Wristify," a thermoelectric bracelet that uses alternating pulses of hot or cold to regulate the temperature of the person wearing it.
The ‘Wristify’ prototype won first place at the MADMEC, an annual competition put on by the school’s Materials Science and Engineering program.
In the U.S. alone air conditioning accounts for 16.5 percent of energy use. If ‘Wristify’ becomes available for public use, it will certainly contribute to lessening the energy problem the world is currently facing, because you will not need air conditioning if you can control your body’s temperature!
