This research is a study on the development of a new tribosensor that has the sensibility of human finger. The sensor is basically a piezoceramic AE sensor. It is placed and moved on the material to be identified. The voltage signal from the sensor is first stored in the digital memory for a fixed period of time. It is then analyzed to obtain the maximum signal strength, the total number of concaves and convexes of the signal, and the number of crossings with the line of mean signal strength. Each set of the parameters obtained is compared with the training set of data in the neural networks, and the material of the measured sample is fixed. Experimental results obtained show that the present sensor system identifies the material 85% correctly for 120 samples of 6 different materials and the correct recognition is rised to 95% by two step assortment.

本研究旨在研制一种具有人手指敏感性的新型摩擦传感器。该传感器基本上是压电陶瓷AE传感器。它被放置在待识别的材料上并移动。来自传感器的电压信号首先存储在数字存储器中一段固定的时间。然后分析以获得最大信号强度、信号的凹部和凸部的总数以及与平均信号强度的线的交叉数。将获得的每组参数与神经网络中的训练数据集进行比较，并固定测量样品的材料。实验结果表明，该传感器系统对6种不同材料的120个样本的识别正确率为85%，通过两步分类，正确识别率提高到95%。
