Modern wearable electronics have a lot of positive things, but many instances (take at least the same smart watch) have one major drawback: fast discharge of the battery. Agree, such gadgets can hardly be called convenient and mobile, if you depend on the outlet. But researchers from the University of Texas A & M managed to create a new type of supercapacitor capable of charging from both the mains and the heat of the human body.
The group of scientists responsible for the invention is headed by Dr. Chuong Y. The capacitor is called the Thermally Chargeable Solid-state Supercapacito (temperature rechargeable solid-state supercapacitor). Using this type of device may well replace standard batteries in wearable electronics. According to Dr. Chuong Yu,
“Our case is the first of its kind when it was possible to achieve the production of electrical energy directly from heat using a special solid polymer electrolyte. Heat causes the formation of local high-voltage electric fields inside a polymer electrolyte, then this voltage serves as a catalyst for electrochemical reactions, which charge the supercapacitor. Our supercapacitor allows you to realize the supply of electrical energy in a completely new way, without the need for an external power source or the periodic replacement of batteries. "
In the hands of the inventors, a new supercapacitor, which in the future may save us from daily charging of wearable electronics
Among other things, the new device is quite thin (about 3-4 millimeters) and flexible. The basic principle of operation is such a property as thermal diffusion. Due to thermal diffusion under the influence of temperature, the ions move from the hotter side to the cooler side, and the electrochemical potential resulting from this phenomenon ensures the charge of the supercapacitor.
