本研究之目的為透過改變介電層的結構設計以降低感測器之結構剛性，在不影響空間解析度的前提下，達成增加疊加型電容式觸覺感測器之感測靈敏度(Sensitivity)的成果。
本研究透過實驗證明，將彈性體介電層由實心結構更改為空心結構時，可以大幅度提升感測器的感測靈敏度。在正向施力為0.25 N時，空心結構之平均感測靈敏度為31.660 pF/N，為實心結構的597.4倍。而在剪力施力為1.5 N時，空心結構之平均感測靈敏度相較於實心結構在各個施力角度下也至少提升5.61倍的感測靈敏度。透過剪力角度公式分析，量測角度與施力角度之誤差在各方向下皆小於4°。
由研究之成果可知，透過更改介電層之結構以降低結構剛性，可大幅提升感測靈敏度，且可以保有原先設計之高空間解析度及角度量測功能。

The purpose of this study is to improve the sensitivity of stacked capacitive tactile sensors by changing the dielectric layer from solid to hollow to reduce the structural rigidity of the sensor. The result indicated that the sensitivity can be enhanced without affecting spatial resolution.
When the normal force is 0.25 N, the average sensitivity of the hollow structure is 31.660 pF/N, which is 597.4 times that of the solid structure, displaying great sensitivity enhancement. When the shear force is 1.5 N, the average sensitivity of the hollow structure is at least 5.61 times the sensitivity of the solid structure for all shear angles. Analyses also indicated that the error between the measurement angle and shear force application angle is less than 4°.
