CAPACITIVE MATRIX PRESSURE SENSOR Russian patent published in 1994 - IPC

Abstract SU 1593388 A1

FIELD: measurement technology. SUBSTANCE: sensor has three dielectric layers of varnish composing 3, 3′, 4, 4′-diphenyltetracarbonic acid dianhydride and 4, 4′-diaminodiohenolic ester dianhydride. Varnish is not subject to hydrolysis reactions and is resistant to other chemical agents, therefore it possesses high moisture resistance within comprehensive temperature range. EFFECT: improved moisture resistance and chemical resistance. 4 dwg
