本研究為應用生物阻抗量測於保健上。生物阻抗法是用來量測生理參數來研究身體組織結構狀態，作法是利用二電極注入一時變電流並用另二電極量測待測物電位差，此電壓訊號為複數訊號，經由解調變之後，可得0度與90度向量，亦為電阻與容抗向量。人體可用電阻與電容並聯模型來表示，當量測到容抗與電阻，即可得知身體組織狀況，其中容抗與細胞數有關，電阻與傳導路徑有關。
整個系統包含了類比信號量測及處理模組，ARM處理器模阻以及可在WINCE下執行之分析程式，採用觸控螢幕來做為顯示及控制單元，可有效減少體積與操作更容易。

　This study shows how to apply the bioelectric impedance measurement into personal health care. Electric impedance methods are used to measure physiological events and to investigate tissue structure.
Bioelectric impedance signals are obtained by injecting an alternating current of known amplitude and frequency, carrier signal, through two electrodes fixed on the skin, and measuring the resulting voltage drops using a different pair of electrodes.
What is the circuit of the human body? It can be modeled as the network of resistors and capacitors. So we can measure the resistance and reactance to account for human body status.
The system consists of analog signal processing module, Arm-based microcomputer module and an program written by WinCE language. Using touch panel be display and control unit, it can effectively reduce the volume of hardware and make the operation easier.
