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. 相似文献

We consider distributed state estimation over a resource-limited wireless sensor network. A stochastic sensor activation scheme is introduced to reduce the sensor energy consumption in communications, under which each sensor is activated with a certain probability. When the sensor is activated, it observes the target state and exchanges its estimate of the target state with its neighbors; otherwise, it only receives the estimates from its neighbors. An optimal estimator is designed for each sensor by minimizing its mean-squared estimation error. An upper and a lower bound of the limiting estimation error covariance are obtained. A method of selecting the consensus gain and a lower bound of the activating probability is also provided. 相似文献
