A Study on the Development and Characteristics of Strain Gauge using Sputter Machining

스파타가공법을 이용한 스트레인 게이지의 개발 및 특성에 관한 연구

The control of resistance of foil strain gauge is accomplished by means of etching technique. Thus, there is an irregularity in metal foil. In order to solve this problem, ion sputter machining method has been used to make strain gauge in this study and the characteristics of this strain gauge are investigated. As the result of this study, it was possible to make a flexible strain gauge which can be used to measure the stress. The strain gauge made by authors shows superior characteristics in creep, O point variance, hysteresis and nonlinearity by surrounding temperature.
