We plan to design a TETS having the following specifications.
・High energy transmission efficiency (90-98%)
・High power transmission (10m - 40W)
・Free from biological effects

A transcutaneous energy transmission system (TETS) is a transmission system for implantable medical devices, based on electromagnetic induction.


Power source of implantable medical devices (Left ventricular assist device, pacemaker, ICD, capsule endoscope, implantable sensors, etc.)

This method can improve the quality of life (QOL) of a patient and reduced the risk of infection relative to percutaneous connections.
