Patent ID: 8294226

Claim:
A large surface distributed pressure sensor for distinguishing a plurality of magnitudes of a pressure on a sensor area of at least 1 cm×1 cm, the large surface distributed pressure sensor comprising: a first flexible substrate and a second flexible substrate, the first flexible substrate being partially coated by a layer of polythiophene comprising repetitive structural units with formula (I), wherein R 1 and R 2 are independently a C 1 -C 12 alkyl group or R 1 and R 2 form a C 1 -C 12 1,n-alkylene group, n=1-12, optionally substituted by a C 1 -C 12 alkyl group, C 2 -C 12 alkene, vinylene, benzyl, phenyl group, a halogen atom, or by an ester, amine, amide or ether functional group, optionally substituted by a C 1 -C 12 alkyl group; and an insulating spacer.
