Biocompatible implant electrodes operating in body fluid for energy storage devices |
| 초록 |
Implantable electronic medical devices (IEMDs) can potentially be used to solve various clinical problems including monitoring chronic diseases and electro-organ transplantation. We describe a new technique for IEMDs that is capable of providing energy storage using natural ions in body fluids as electrolytes for a supercapacitor. The system is constructed with a solar cell for energy harvesting and a supercapacitor for energy storage. By assembling IEMDs with two biocompatible electrodes—MnO2 nanoparticles affixed to multiwalled carbon nanotubes as the positive electrodes and phosphidated activated carbon as the negative electrodes, this technique avoids the problems of performance degradation and toxicity. These two biocompatible electrodes were successfully implanted into the subcutaneous layer of rat skin, with both electrodes showing stable performance as a supercapacitor. These findings establish a platform for potential biocompatible materials for implantable energy storage devices. |
