POLYTHIOPHEN-BASED DISTRIBUTED PRESSURE SENSORS HAVING A LARGE SURFACE AREA

摘要

The present invention relates to large surface distributed pressure sensors comprising at least two flexible substrates, at least of one of these being entirely or partially coated by a layer of polythiophene containing repetitive structural units with formula (I),
wherein R 1 and R 2 are independently a C 1 -C 12 alkyl group or they form a C 1 -C 12 1,n-alkylene group, with 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 one or more insulating spacers. Said sensors are flexible and easy to manufacture and they may present different symmetric, simple or multilayer configurations, as desired.
