本研究之目的在於不完全犧牲感測靈敏度的前提下，提升電容式觸覺感測器對於正向力量測之工作範圍。
本研究藉由在原有結構層上增加緩衝結構，使得元件受正向力作用時，有兩階段的剛性變化。利用第二階段較大的剛性，犧牲部分靈敏度，來達到擴大工作範圍，並藉由改變緩衝結構的位置，讓使用者能取捨靈敏度及工作範圍。
結果顯示，緩衝結構能顯著增加感測器的工作範圍。且緩衝結構被配置於不同位置時，呈現不同程度之效果，最大可增加135.3%之工作範圍。

The purpose of this study is to enlarge the operating window of capacitive tactile sensors for normal force detection without completely sacrificing its sensitivity.
In this study, by adding stoppers, the sensors under normal force have a two-stage rigidity change. The increased rigidity of the second stage sacrifices a part of the sensitivity to achieve an expansion of the operating window. By changing the stopper’s location, it shows operation flexibility between sensitivity and operating window.
Results show that the stopper significantly increases the operating window of the capacitive tactile sensor, displaying different performances at different locations. The operating window was increased by most 135.3% in this study.
