Title
(EN) PRESSURE SENSOR AND DISPLAY DEVICE
(FR) CAPTEUR DE PRESSION ET DISPOSITIF D'AFFICHAGE
(JA) 押力センサ及び表示装置
Abstract
(EN)
This pressure sensor comprises a first electrode, a second electrode, a first conductor that faces the first electrode in a first direction, a second conductor that faces the second electrode in the first direction, and a first elastic member and a second elastic member that are arranged between the first electrode and the first conductor, the first elastic member being arranged between the second electrode and the second conductor, and the degree of compression of the first elastic member and the second elastic member in relation to pressure differing in accordance with the temperature.
(FR)
L'invention concerne un capteur de pression comprenant une première électrode, une seconde électrode, un premier conducteur faisant face à la première électrode dans une première direction, un second conducteur faisant face à la seconde électrode dans la première direction, et un premier élément élastique et un second élément élastique agencés entre la première électrode et le premier conducteur, le premier élément élastique étant agencé entre la seconde électrode et le second conducteur, et le degré de compression du premier élément élastique et du second élément élastique par rapport à la pression différant en fonction de la température.
