Abstract

L'invention concerne un coussin et un oreiller d'acquisition de signal de pression. Le coussin d'acquisition de signal de pression comprend une couche souple (10), une couche sensible à la pression (20), et une partie pression (30). La couche sensible à la pression (20) est disposée de manière fixe sur la couche souple (10). La couche sensible à la pression (20) comprend un film piézoélectrique (21). La partie pression (30) est disposée sur la couche sensible à la pression (20). Lorsque la partie pression (30) et la couche souple (10) font pression l'une contre l'autre, la partie pression (30) fait pression sur une partie de la couche sensible à la pression (20) qui est en contact avec la partie pression (30) vers la couche souple (10). La couche souple (10) au niveau de cette position s'enfonce le long d'une direction de contrainte, et correspondant à une zone circonférentielle de la partie pression (30), la couche souple (10) au niveau de cette position soutient la couche sensible à la pression (20), ce qui provoque une déformation à la traction de la couche sensible à la pression (20) et permet ainsi la génération d'un signal électrique. Le coussin et l'oreiller d'acquisition de signal de pression ont une structure simple, qui facilite la production en masse. En outre, lorsque la partie pression (30) fait pression sur la couche sensible à la pression (20), la déformation de la couche sensible à la pression (20) est uniforme sous l'effet de la couche souple (10), permettant de réduire un taux de détérioration de la couche sensible à la pression, et de prolonger une durée de vie du coussin d'acquisition de signal de pression.
