摘要:
The present invention provides a pressure sensor comprising: a first electrode located on a first substrate and including a plurality of first metal patterns having a certain interval; a second electrode located on a second substrate and including a plurality of second metal patterns having a certain interval; and an insulating layer located between the first metal patterns and the second metal patterns and including a plurality of through holes having a certain interval, wherein the first metal patterns connect one end and the other end of the first substrate, the second metal patterns connect one end and the other end of the second substrate in the direction perpendicular to the first metal patterns, and the plurality of through holes are located on the first metal patterns and the second metal patterns. The pressure sensor of the present invention comprises the insulating layer located between the pixelated electrode layers and having the holes at pixel locations, to thereby allow the upper and lower electrodes to be electrically connected only when pressure is applied. Therefore, the mechanical interference of signals due to the response of surrounding pixels during the application of pressure is reduced, and selective sensing is possible due to the interpixel insulation by the inserted interlayer. Also, the pressure sensor of the present invention may allow a pressure sensing range to be controllable through adjustment of the material and thickness of the insulating layer and adjustment of the size of the holes included in the insulating layer. Also, the pressure sensor according to the present invention is manufactured by a simple process, has a simple structure, and is flexible and wearable, and thus is applicable to electronic devices and electronic skin for robots.La présente invention concerne un capteur de pression, lequel capteur comprend : une première électrode située sur un premier substrat et comprenant une pluralité de premiers motifs métalliques ay
