FIELD: physics.
SUBSTANCE: sensitive device has at least one first layer having an electroconductive polymer, if necessary, mixed with a binding substance, which forms a matrix of a binding agent, and at least one second layer which lies separately from the first layer near or at a distance or which is at least partially joined to the first layer. The second layer has microcapsules which contain acidic or alkaline substance, if necessary mixed with a binding substance and alters electrical conductivity of the polymer when released from the microcapsules.
EFFECT: making sensitive devices for monitoring state of articles.
