Document Type and Number:
WIPO Patent Application WO/2019/047626
Kind Code:
A1
Abstract:
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.
