Researchers have developed a new soft implantable power system for health devices that combines wireless energy transfer and storage.
They were created by utilizing biodegradable Zn-ion hybrid supercapacitors that use molybdenum sulfide (MoS2) nanosheets as cathode, ion-crosslinked alginate gel as electrolyte, and zinc foil as anode for high-performance energy storage.
This technology could revolutionize implantable medical devices like pacemakers and drug delivery systems by providing wireless energy, eliminating the need for surgical battery replacements. This technology is also ideal for health monitoring sensors, advanced prosthetics, and neurotechnology devices.
