A group of researchers at the Massachusetts Institute of Technology developed a button-sized, self-recharging battery. A two-centimeter-wide battery can convert your body's heat into electricity. The device can operate at temperatures of 20 degrees Celsius and 60 degrees Celsius, which are far below other heat collection technologies. Dr. Chen Gang, head of the project led by the Massachusetts Institute of Technology, said: "This technology may generate new cell phone batteries that can be recharged without the need for data line connections. This is a self-powered device and may be Those areas without a grid are attractive."
He said: "In order for the battery to generate enough power for practical applications, such as the charging of mobile phones, we also need to use better materials and system design. We are also working hard on this." Further development It is possible to use this battery for a wider range of applications. The battery rotates using inexpensive materials, which means it can save costs. Dr. Chen believes that its performance can be further improved by improving the material of the battery and adjusting its design.
