碩士 === 國立臺北科技大學 === 電子工程系研究所 === 105 === The implantable stimulator can transfer the power via Wireless Power Transfer Technique and which can also be embedded in the human body. The main function of the implantable stimulator is aim to cure the damaged nerve by way of PRF(Pulsed Radio-Frequency). It can stop the transmitting of the sense of pain and also can accelerate the repair rate of the damaged nerve. This paper purposes two ways to make the implantable stimulator. The first one is chip, which is made by high voltage power process (TSMC 0.25μM CMOS by CIC.) The second one is device, which uses MCU DA14580 as the core. Since the limitation of low voltage power supply, the chip and the device use the high voltage to stimulating. The system uses the way of coupling to transfer the power. The difference between chip and device is how to generate the PRF waveform. The PRF waveform of chip is generated by transmitter, then it coupling receiver to stimulates nerve then the transmitter can got the voltage data by voltage return circuit which in the chip. In device the transmitter only provides voltage that enough to make device work, and it’s PRF waveform generated by PRF driver circuit which in the device. Besides the device also can connect with cellphone through Bluetooth then the user not only can control the frequency of PRF waveform, but also can receive the voltage data.
