Characteristic evaluation of a solid polymer electrolyte sensor

This paper describes a development of a curvature sensor using a solid polymer electrolyte (SPE) film. The SPE film has good flexibility, and can be used in air. In previous research, we clarified output response to deformation of the SPE sensor and the relationship between sensor output and sensor curvature. In this paper, output characteristics of the SPE sensor are investigated in detail. Four sensors with different length and width are prepared. And the influence of the SPE sensor on the sensor element shape is investigated. As a result, it is confirmed that there are a several sensors which cause a slight reduction of the sensor output because it is difficult to place the whole sensor element on the sample curve exactly. Concerning with the large sensor, it was confirmed that the reduction of the sensor output is not occurred.
