5. Summary :
Technology and market together are drastically growing in the area of implantable devices for medical treatment including implantable cardiac defibrillator or deep brain stimulator. However, after 5 to 9 years later, a patient is forced to have surgery just for changing battery. In order to overcome the power limitation of primary battery, wirelessly recharging battery technology has been highly requested. Previous wireless power charging technologies such as magnetic resonance and induction coupling have limited applications because of its short transfer distance compared to device size and magnetic field intensity limitation for the safety of body exposure. As an alternative, the biocompatible wireless power transferring and charging technology is proposed using ultrasonic resonance devices. The ultrasonic resonance transmitter and receiver are manufactured with the size of 30.0 mm diameter, 3.0 mm height. The energy transferring efficiency from input electrical power of transmitter to power of receiver is about 43 % through 10 mm skin tissue, experimentally. The maximum transferring power is up to 150 mW.
The manufactured implantable device has the function of sensing ECoG signal, stimulating spinal cord, wireless data communication and wireless power transferring. Some experimental data of implantable test will be presented.
