摘要

The electronic module e.g. transistor useful in an electronic circuit, comprises two electrically conductive contacts (1, 2) bridged by a molecule (3), a means for impulse transmission, and an active layer (7). The molecule has anchor groups (4, 5), which receive a connection with first and second conductive contacts respectively, and a molecular core (6) having conjugated units. The length is varied between the conductive contacts by creating an impulse to the active layer. The length variation causes a variation of the electrical conductivity between the conductive contacts. The electronic module e.g. transistor useful in an electronic circuit, comprises two electrically conductive contacts (1, 2) bridged by a molecule (3), a means for impulse transmission, and an active layer (7). The molecule has anchor groups (4, 5), which receive a connection with first and second conductive contacts respectively, and a molecular core (6) having conjugated units. The length is varied between the conductive contacts by creating an impulse to the active layer. The length variation causes a variation of the electrical conductivity between the conductive contacts. The impulse is electric, magnetic, thermal and/or thermal nature. The means is formed as electrode or electrode pairs. The active layer contains an electrostrictive polymer, a piezoelectric polymer, a piezoelectric ceramics, a piezoelectric metallic oxide or different combinations of the protruding materials. The active layer contains a shape-memory alloy, shape-memory polymer, electrostrictive polymer, ferroelectric shape-memory alloy, electrorheological fluid, electrorheological elastomer, magnetorheological fluid, magnetorheological elastomer, ionic polymer-metal composite or different combinations of the protruding materials. The active layer contains a natural oxide of the means, and an artificial oxide grown on the means. Both the conductive contacts consist of same material. The anchors groups have same chemical structure. The length variation varies the conformation of the molecule between the conductive contacts and varies the connection of the anchors groups at one of the conductive contacts. The molecule is embedded between the conductive contacts in a matrix of isolating molecules, which prevent an electrical short-circuit between the conductive contacts. The connection between the second anchor group and the second conductive contact is modified by metallic nanoparticles.
