本論文旨在應用感應電能傳輸技術，研製具非接觸式供電監控單元之植入型功能電刺激器，並於架構中加入雙向資料傳輸機制，其特點在於將電刺激器共構於骨折手術中所植入之骨釘內。於操作頻率上選用頻段中心為13.56 MHz之射頻頻率以縮小線圈體積，並根據操作頻率選擇合適之激勵電路，接著利用磁場模擬軟體分析印刷電路板結構磁通密度分布與觀察改變線圈圈數之耦合係數變化，藉此決定體外側、植入側線圈規格。電刺激策略上採用定電流刺激模式，首先於體外側電路加入移幅鍵控調變電路，可根據組織不同復健時期之情形將控制訊號予以植入側電刺激電路俾便改變刺激波形；植入側端加入移載鍵控調變機制，得使患者監控體內狀況而選用適當刺激波形，兩種調變皆允許同一組線圈雙向傳輸資料，有效減少電路體積。當仿體厚度為1.5公分時，於中心位置有最大電能傳輸效率54.1%，當系統達到最大軸向位移下，電能傳輸效率仍能維持於38.2%，以確保植入式骨釘電刺激器之完整運作。

The thesis is aimed to use the contactless power transfer technique combined with electrical stimulation and bi-directional data transmission mechanisms, finally embedded into bone nails. At the first of this thesis, operating frequency has been chosen at 13.56 MHz to reduce the coils volume, different forms of inductive coils are stimulated and analyzed to improve the magnetic field distribution. The strategy of stimulation is current mode, and command data will be supplied to the implantable stimulation module by telemetry utilizing an amplitude shift keying (ASK) to change the output stimulation waveform. For internal side, backward data telemetry was designed by using the reflected impedance property of an inductive couple, which is called load shift keying (LSK), two modulation mechanisms allows data transmission through by using one coupling structure. The highest power efficiency is 54.1% when the gap is 1.5 cm. The efficiency is 38.2% when the coils has maximum misalignment.
