Inexpensive Pressure Distribution Visualization Equipment Using Conductive Rubber

Abstract

　This paper describes the development of pressure distribution visualization device using relatively inexpensive and available materials such as PC keyboard boards and conductive rubber. If the device is cost-cut, it can be widely used in the field of rehabilitation and sports. Conductive rubber is inserted into a keyboard boards for a PC. The pressure can be estimated by measuring the resistance at each point. In this study, the basic performance of the prototype sensor was investigated by investigating changes in the thickness of the conductive rubber and the resulting changes in resistance from a quantitative perspective. As a result, proposed method can be useful to measure the pressure distribution under static conditions and sufficiently long time conditions.
