FIELD: electronics.
SUBSTANCE: device contains substrate-based film on the basis of polarised ferroelectric - lead circonate-titanate with double-side electrode coating, which is semi-transparent from external side of film. In order to increase device reliability by provision of its operation in static mode film of lead circonate-titanate is made as polycrystals in matrix of lead oxide.
EFFECT: higher accuracy and reliability of operation.
