Russia’s National University of Research Technology has developed a new heatbox device that converts heat into electrical energy, allowing it to charge various electronic devices using human body temperature. The findings are published in the journal Renewable Energy.
The idea of using body temperature to generate electricity is not new, but previous devices of the same kind have failed to provide enough power for the charging unit. For the first time, Russian scholars have developed a new type of heat box using oxidizing metal electrodes and hydrolyte-containing electrolytics. This solution helps to increase current and reduce internal resistance, which greatly increases electrical energy compared to comparable products.
Igor Burmistrov, a researcher in the University’s Department of Basic Nanosystems and High Temperature Materials, explains: “We designed a heatbox device that can be fixed to clothing and power electronics using body temperature and the environment. Temperature gradients exist everywhere and surround us, and this type of device helps absorb the energy emitted into the environment by industrial facilities, buildings and other energy sources. “
In the future, researchers plan to make electrochemical condensers that can be charged in simple contact with heated surfaces and charged for long periods of time.
