Title (EN) PRESSURE SENSOR AND PRESSURE DETECTION METHOD
(FR) CAPTEUR DE PRESSION ET PROCÉDÉ DE DÉTECTION DE PRESSION
(ZH) 压力传感器和压力检测方法
Abstract:
(EN) A pressure sensor and a pressure detection method, the pressure sensor comprising: a liquid crystal box (1) which comprises a cholesteric liquid crystal layer (2), a liquid crystal state detection module and a pressure querying module, wherein the liquid crystal box (1) is provided with a press face. The liquid crystal state detection module is used for detecting the liquid crystal arrangement state in the cholesteric liquid crystal layer (2) when pressure is applied to the press face of the liquid crystal box (1); and the pressure querying module is used for querying from a prestored correspondence relation table the magnitude of the pressure corresponding to the liquid crystal arrangement state.
(FR) L'invention concerne un capteur de pression et un procédé de détection de pression, le capteur de pression comprenant : une boîte à cristaux liquides (1) comprenant une couche de cristaux liquides cholestériques (2), un module de détection d'état de cristaux liquides et un module d'interrogation de pression, la boîte à cristaux liquides (1) comprenant une face de pression. Le module de détection d'état de cristaux liquides est utilisé pour détecter l'état d'agencement de cristaux liquides dans la couche de cristaux liquides cholestériques (2) lorsqu'une pression est appliquée à la face de pression de la boîte à cristaux liquides (1) ; et le module d'interrogation de pression est utilisé pour interroger à partir d'une table de relation de correspondance préenregistrée l'amplitude de la pression correspondant à l'état d'agencement de cristaux liquides.
(ZH) 一种压力传感器和压力检测方法,该压力传感器包括:含有胆甾型液晶层(2)的液晶盒(1)、液晶状态检测模块和压力查询模块,液晶盒(1)具有受压面。液晶状态检测模块用于在液晶盒(1)的受压面被压力作用时检测胆甾型液晶层(2)内的液晶排布状态;压力查询模块用于从预先存储的对应关系表中查询出与液晶排布状态对应的压力的大小。
