The respondent properties of the textile pressure sensors-the evaluation of compression properties of the multi-layer textile

There are various seat-type pressure sensors but there are no seats, which fulfill all the conditions such as flexibility, expandability, thinness and low cost. Then we developed a new pressure sensor using the compression property of fabric. In this report, we evaluated the respondent properties of the fabric sensor. It turned out its response time when to detect pressure is about 0.1 ms. Also it turned out that the frequency range of detection is about 30 Hz considering the strain of fabric when to pressure the fabric repeatedly. And depending on the conditions of the finished work such as sandwiching the fabric between rubber boards, the frequency range even decreases. © 2010 The Textile Machinery Society of Japan.
