摘要：
The present invention provides a pressure sensor comprising: a first electrode which is positioned on a first substrate and includes a plurality of first metal patterns having prescribed intervals； a second electrode which is positioned on a second substrate and includes a plurality of second metal patterns having prescribed intervals； and an insulation layer which is positioned between the first and second metal patterns, has prescribed intervals, and includes a plurality of penetration holes. The first metal patterns connect one end and the other end of the first substrate, and the second metal patterns connect one end and the other end of the second substrate in the perpendicular direction with respect to the first metal patterns. The plurality of penetration holes are positioned on the first and second metal patterns. The pressure sensor includes the insulation layer having holes at pixel positions between pixelated electrode layers to conduct electricity through an upper and a lower electrode only when a pressure is applied, so as to reduce mechanical interference of signals in which surrounding pixels react together when a pressure is applied. In addition, selective sensing is possible due to insulation between pixels by the inserted intermediate layer. The pressure sensor can also adjust the material and thickness of the insulation layer and adjust a pressure recognition range by size adjustment of the holes included in the insulation layer. Also, the pressure sensor is manufactured by a simple process, has a simple structure, is flexible, and is wearable to be applied to electronic devices and robot electronic skin.COPYRIGHT KIPO 2020본 발명은 제1 기판 상에 위치하고, 소정의 간격을 갖는 다수의 제1 금속패턴을 포함하는 제1 전극； 제2 기판 상에 위치하고, 소정의 간격을 갖는 다수의 제2 금속패턴을 포함하는 제2 전극； 및 상기 제1 금속패턴 및 제2 금속패턴 사이에 위치하고, 소정의 간격을 가지고 있고, 다수의 관통홀을 포함하는 절연층；을 포함하고, 상기 제1 금속패턴이 제1 기판의 일단과 타단을 연결하고, 상기 제2 금속패턴이 제1 금속패턴에 대하여 수직 방향으로 제2 기판의 일단과 타단을 연결하고, 상기 다수의 관통홀이 제1 금속패턴 및 제2 금속패턴 상에 위치하는 것인, 압력센서를 제공한다. 본 발명의
