Abstract
A pressure sensor and a pressure detecting method are provided, the pressure sensor includes a liquid crystal cell including a cholesteric liquid crystal layer, a liquid crystal state detector module and a pressure finder module, and the liquid crystal cell includes a pressure receiving surface. The liquid crystal state detector module is configured to detect a liquid crystal arrangement state in the cholesteric liquid crystal layer in a situation where a pressure is applied on the pressure receiving surface of the liquid crystal cell; the pressure finder module is configured to find a value of the pressure corresponding to the liquid crystal arrangement state from a pre-stored correspondence table.
