摘要:	本論文中，將利用量測血糖方式，將可以量測血糖試紙改成可以量測三酸甘油脂的試紙，然後再將家用式血糖機改成家用式三酸甘油脂機器。試紙原理是利用電化學原理，將三酸甘油脂分解成H2O2，然後再藉由氧化還原方式將H2O2釋放出電子，家用型三酸甘油脂機器在印上導電碳的試紙之工作電極加上電壓，讓電子被被吸到導電碳上，形成電子流。然後家用型三酸甘油脂機器再藉由電子流轉電壓方式讀取訊號。但也因為訊號太小，需要利用訊號放大器將訊號放大，將原來的非線性關係回歸到線性關係而得到線性方程式，配合數位轉邏輯可以得到線性比例並利用標準品校正線性方程式參數，而可以得到血清中的三酸甘油脂濃度，顯示在機器的螢幕上。 ;In this thesis, glucose measurement methodology was used to modify the glucose test strip to test triglyceride and hence change the home-use glucose test meter to home-use triglyceride test meter. Through electrochemistry principle of the strip, triglyceride was first breaks into H2O2, and electron was being released through oxidation reduction process which was then being captured by the carbon-printed electro circuit board of test strip, which was being given with certain electric voltage by the home-use triglyceride test meter, to form electro current while the voltage generated was received by the meter. OP amplifier used not only amplifies the micro current, but also regresses the signal to be linear regression concurrently. Through A/D conversion, the linear regression was then proportional to the triglyceride concentration in the sample. With the standard calibration parameter, triglyceride in the blood serum sample was capable to be calculated and displayed on the meter’s liquid-crystal display.
