Development of a strain sensor matrix on mobilized flexible substrate for the imaging ofwind pressure distribution

Abstract

This paper presents a novel flexible sensor formonitoring wind pressure distribution. Based on the concept of "flexible mechatronics", a suspended structure was incorporated into the matrix of a resistive-strain sensor in a plastic film to make the sensor mechanically movable against the wind. Screen printing and laser cutting were confirmed to be satisfactory methods for fabricating the proposed device structure. As a result, the visualization of wind pressure was successfully demonstrated by the fabricated sensor sheet and an imaging-display-creation software. The results of this study show that a mechanically functionalized substrate opens up new avenues for flexible electronics.
