Abstract :
Inductive coupling is frequently used for power transfer to implanted electronic devices. Transcutaneous power link design for implanted systems is presented in this paper. MEMS coils which are fabricated with micromanufacturing technology are also tested as receiver coils. The class-E transmitter circuit uses a 5V supply and resonates at a frequency of 1.068 MHz. The peak of transmitter coil current is 400 mA. Using regular receiver coil with diameter of 3 cm and employs high-Q wire can receive 40 mW power. Results of using MEMS coil, the maximum receive power is -41 dBm.
