Abstract
This paper presents a novel flexible sensor for monitoring 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.
Highlights
Flexible electronics have attracted increasing attention in recent years
We fabricated a sheet with a wind pressure distribution sensor by combining a resistive-strain sensor matrix and an individual moving structure composed of film substrate
We developed a new sensor matrix based on the concept called flexible mechatronics to evaluate wind pressure distribution
Summary
Devices fabricated on thin flexible films can provide attractive features, such as the comfort of portability by rolling up or folding of the devices. Owing to their flexibility, they can be fixed on curved surfaces. Sensor matrixes with large areas have been demonstrated to detect the distribution of physical quantities, such as pressure [7,8,9]. The industrialization of such large-area sensors requires an improved manufacturing process that can efficiently process the large areas. Printing technology was developed to create functional layers in the atmosphere without the use of photoresists and the etching process [10,11,12]
