Abstract
A pressure sensing method and a system thereof are disclosed. The pressure sensing method includes following steps. Stored resistance values Rare read and a differential resistance value ΔRbetween resistance valises at adjacent moments are calculated. At least one ΔR/Ris obtained. The at least one ΔR/Ror a sum of plural ΔR/Ris compared to at least one predefined database. A pressing force value Fcorresponding to the at least one ΔR/Ror the sum of the plural ΔR/Ris obtained, so as to detect and process a pressure sensing signal precisely.
