Title:
WEARING-PRESSURE MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP2719090
Kind Code:
B2
Abstract:
PURPOSE: To provide a wearing-pressure measuring apparatus wherein the wearing pressure of even a complicated three-dimensional curved surface can be measured with good accuracy and the distribution of a pressure on a measuring face can be measured precisely.
CONSTITUTION: This measuring apparatus is provided with a pressure sensor 10 which is constituted of a pressure-sensitive sheet 9 composed of a pressure- sensitive and conductive elastomer displaying a change in a resistance value having a significant difference within a load range of 0.1 to 200g/cm2 and of expansive and contractive electrodes 8 constituted so as to hold linear conductive parts 2 on expansive and contractive base materials 3 and which is fitted to a three-dimensional curved surface. In addition, a plurality of the linear conductive parts 2 for the expansive and contractive electrodes 8 are arranged so as to be mutually orthogonal, and the distribution of a pressure can be measured.
