動物行為量測是利用儀器將動物在空間中的行為變化加以偵測的一種技術，動物的行為變化資訊是醫學動物實驗中一項極為重要的實驗數據，例如：各種藥物對動物的影響、外在環境對動物的影響、刺激或抑制動物的神經系統對動物的影響，動物行為的變化情形都是非常重要的實驗參數。如何能精確且自動的量測出動物受到各種外在因素影響所造成的行為變化，這是本研究的主要目的。
本論文中提出了一種以自製的震動感測元件來量測動物行為的構想，由於此元件可以量測出極微小的物體震動，所以我們希望能利用此元件來量測一些微小的動物行為，如動物的心跳、動物身體的抖動…等，目前已完成之雛形系統係使用一包含四顆24位元之高解析度類比數位轉換器的多通道數據擷取系統，此系統包含一單晶微處理器，它的作用是將所擷取之資料送至個人電腦進一步顯示、分析、及記錄，而且經過我們對自製的震動感測元件作特性測試後發現此元件比市面上販售的工業用標準電容式加速度計靈敏十倍以上。

The animal behavior measurement is a technology using an instrumentation to measure the motion of animal in an open field. Animal activity is a very important experimental parameter for many research, such as pharmacology, toxicology, physiology…etc. The main purpose of this research is to find an automatic measurement method which can measure the animal behavior variance between different experimental environment with enough accuracy.
The idea to measure animal activity is using a vibration sensing element which produced by ourselves is introduced in this study. Base on the sensitivity of this element, we wish to measure some small behavior produced by animal, such as heartbeat, shake…etc. The prototype system include the multi-channel data collection system which has four 24 bits high resolution analog to digital converter. The data collection system has an microprocessor which can transmit data to PC for further display, analysis, and record. After testing of this sensing element, we find out that the sensitivity of this sensing element is better ten times than the commercial capacitive type accelerometer.
