The idea of body heat charging treasure comes from a lecture given by students in Gang Lin, Nanjing University of Information Science & Technology on 20 13. At that time, the school was preparing for the "Challenge Cup" competition for college students, hoping that students would actively participate. A girl in Canada made a flashlight, which can illuminate without batteries. Its technical principle is to use the temperature difference to convert the thermal energy of the body into electric energy.

That night, Gang Lin basically decided his research direction. But at that time, I just thought that this research was not too difficult and a little innovative, and I didn't want to do anything with it. Then I bought a charging treasure and found that it was not very easy to use before I found a clear design goal. Students thought of a charging treasure, and its effect was very different from that advertised. You can make a charging treasure that can be charged without plugging in.

At the end of 20 13, Gang Lin officially started his scientific research. Check the latest papers in foreign scientific and technological circles, buy raw materials for processing, and measure data in the laboratory.

In May 20 14, the sample of body heat charging treasure was made. According to the laboratory data, the conversion rate of heat and electric energy of his charging treasure sample can reach 17%, and the Apple mobile phone can be fully charged in the hand for two hours.
