A MIT student invents a device that adjusts to a comfortable body temperature simply by attaching it to the arm

Summer is hot and sweat slows out, and it is cold in winter and I can not get out of the futon easily ... ... It may be that the world that does not want such thought is coming soon.Massachusetts Institute of Technology(Hereinafter MIT) student 4 team The device invented by "Wristify" measures the temperature outside just by attaching it to the arm and adjusts the body temperature automatically to comfortable temperature.

This temperature regulation wrist band is a device that monitors air and skin surface temperature and keeps body temperature at a comfortable temperature by sending "hot" or "cold" signals to the wrist. MIT's 4 students team Wristify developed and this yearMADMECI won the first prize at 1 million dollars (about 980,000 yen).

Originally MADMEC and MITDMSEIt is led by,BPYaSaint-Gobain,Dow ChemicalCompetition for companies to sponsor such as. It was held once a year, and it was held for the seventh time this year.

In this competition, three to five students gather together to form a team, each team will prototype the product according to the theme of the competition. Each team will receive 1,000 dollars (about 98,000 yen) as creative funds. Every month after the project starts in June, checks are done and we will gradually shape the prototype of each team. In the middle of this development Wristify,Human skin is also very sensitive to slight irritation, body temperature changes soon, its change extends to the whole bodyI will make a discovery.


By utilizing this phenomenon 0.1C per second (Coulomb) It is also found that it is possible to raise or lower the body temperature of the whole body by applying a load more than that. Wristify creates 15 prototypes based on these findings and finally completes a wristband type prototype that can drive for 8 hours with one lithium polymer battery. This prototype generates electric charge within 0.1 to 0.4 C / sec, and is made of a copper alloy for dissipating the heat of the main bodyheat sink, An automated control system that manages the strength and duration of the heat pulse sent to the heat sink, parts such as the thermometer necessary to measure the outside temperature and adjust body temperature accordingly.


It is said that 16.5% of the energy currently consumed in the US is used for air conditioning and heating, but if the temperature control of the human beings can be perfectly performed by Wristify's body temperature control wristband, energy consumption used for air conditioning There is also the possibility of drastically decreasing it.
