Title (EN) PRESSURE SENSOR AND PRESSURE SENSING DEVICE COMPRISING SAME
(FR) CAPTEUR DE PRESSION ET DISPOSITIF DE DÉTECTION DE PRESSION LE COMPRENANT
(KO) 압력 감지 센서 및 이를 포함하는 압력 감지 장치
Abstract: front page image
(EN)A pressure sensor according to an embodiment of the present invention comprises: a first electrode layer; a second electrode layer; and an intermediate layer disposed between the first electrode layer and the second electrode layer, wherein the intermediate layer changes in resistance, depending on a change in at least one of thickness and volume thereof. In addition, the intermediate layer comprises: a foam having porous regions dispersed in a non-porous region thereof; and a conductive material being dispersed in the foam and greater in conductivity rate than the foam.
(FR)La présente invention concerne un capteur de pression qui, selon un mode de réalisation, comprend : une première couche d'électrode ; une seconde couche d'électrode ; et une couche intermédiaire disposée entre la première couche d'électrode et la seconde couche d'électrode, la couche intermédiaire changeant de résistance, suivant un changement de son épaisseur et/ou de son volume. De plus, la couche intermédiaire comprend : une mousse qui comporte des régions poreuses dispersées dans une région non poreuse de ladite mousse ; et un matériau conducteur qui est dispersé dans la mousse et qui présente un taux de conductivité supérieur à celui de la mousse.
(KO)본 발명의 한 실시예에 따른 압력 감지 센서는 제1 전극층, 제2 전극층, 그리고 상기 제1 전극층과 상기 제2 전극층 사이에 배치되는 중간층을 포함하며, 상기 중간층의 두께 및 체적 중 적어도 하나의 변화에 따라 상기 중간층의 저항이 변화한다. 또한, 상기 중간층은 비공극 영역 내에 공극 영역이 분산된 폼, 그리고 상기 폼 내에 분산되며, 상기 폼보다 도전율이 큰 전도 물질을 포함한다.
