Used methods to wirelessly powered implantable medical devices

The use of implantable medical devices is in remarkable growth. They have used to replace organ's function or to assist an organ to function properly. Implant's designs tend increasingly to the miniaturization (micro/ nanotechnology) in order to be more biocompatible and comfortable. Any time the implant needs energy to function properly. Have efficient, secure, biocompatible and healthy implant system charging remains a challenge. This paper presents a comprehensive review of proposed methods to power up implants. All techniques have been discussed, to present finely the optimal used one.
