New heart implants become wirelessly powered

Since their introduction into medical science, the only way to power implants inserted in the human body was by battery. However, that meant that the power could run out, and further surgeries are needed to replace the power packs. This just put further stress onto the patient, and sometimes rendered the treatment less successful.
But things may be different in the not too distant future. Electrical Engineers at Stanford have found a way around the problem. They have developed a working prototype for a cardiac device that uses both inductive and radiative power transmission, eliminating the need for batteries and allowing wireless charging.
The engineers had a couple of problems to overcome to make this possible.
