本論文主要由兩個研究主題所組成：
一個人體傳輸的在數位調變下的位元錯誤率，並在透過壓電晶體(Piezo)達成傳輸訊號的實現
第一個主題探討各種數位調變的特色與目前應用現狀，並以LabView 進行摸擬傳輸器的運作。在透過壓電晶體(Piezo)做為傳輸界面，通過高通濾波器移除雜訊的干擾，計算出資料傳輸的正確率後，本論文提出為何使用OOK 做為人體傳輸資料的原因。
第二個主題探討人體傳輸系統的設計與實踐 。最後用TSMC 0.35μm 2P4MCMOS 製程設計此應用電路之晶片

This thesis consists of two subjects of research: A Digital Modulation bit error rate study for transmission using the human body as the transmission channel, and signal coupling using a piezo transducer.
The first topic involves studying several kinds of Digital Modulation and application; the transceiver is implemented using LabView. The interface for transmission uses Piezo film transducers. A high pass filter is used to remove noise and interference. The bit error rate using Manchester-coding is measured. A brief discussion is presented justifying the choice of On-Off Keying (OOK) modulation to transmit data on the human body.
The second topic is a study on the design and implementation of a human body transmission system. A test chip is designed in TSMC 0.35μm 2P4M CMOS process and first measured results are presented.
