PRESSURE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensor having excellent conductivity, an excellent electromagnetic shielding effect, and a satisfactory pressure sensitive characteristic. SOLUTION: This pressure sensor detects pressure by a material comprising mainly a light absorbing or light emitting polyphenyl acetylene polymer expressed by a general formula 1 (in the formula, R represents an alkoxy group, Z1, Z2, Z3, Z4are substituents including respectively and independently hydrogens, hydrocarbon group or hetero atoms, and n is an integer 10 or more).
