本研究主要是設計一套可描繪輪廓電極陣列系統。整個系統包含機構、硬體及軟體設計。系統中的電位計則是用來取得電極的位置。而軟體設計則包含了資料擷取程式和輪廓量測程式的使用者介面。感測器的伸長量是透過RS-232串列傳輸埠傳輸至電腦 , 而後再使用這些資料以獲得量測部位的輪廓。三個橢圓柱用來驗證輪廓描繪電極陣列系統的誤差。量測結果的平均誤差大約為3mm。總之本系統有以下特點:1.) 模組化電路設計以方便檢修及整合，2.) 使用單晶片微處理器以簡化電路設計，3.) 方便從系統中更換電極，以及4.) 方便取得電極的空間位置和描繪出量測部位的輪廓。

　　The purpose of this study is to design the contour-tracing electrode-array system. The system contains the mechanical, hardware and software design. The potentiometers are used to obtain the locations of the electrodes. The software design includes the graphic user interface of data acquisition program and the graphic user interface of contour measurement program. The elongation amounts of the sensors are transmitted via RS-232 to the personal computer and then these data are used to obtain the contour of the measurement position. Three elliptic cylinders are used to verify the error of the contour-tracing electrode-array system. The average error of measurement results is about 3mm. After all, the features for the system are: 1.) Convenience in debugging and integration with the modularized circuit design, 2.) Simplification in circuit design using the single-chip microprocessor, 3.) Replace the electrodes conveniently from the system, and 4.) Obtain the spatial positions of electrodes and trace the contour of measurement position conveniently.
