Composite actuators consisting of sheets of the solid polymer electrolyte (similar to Nafion ® ) with Cu 2+ counter ions inserted and coated with platinum and copper metal layers (so-called ionomeric polymer–metal composites; IPMCs) have been synthesised and their electromechanical performance upon actuation has been monitored. Resistance measurements on the electrodes show that the...
The arrangement of antennal sensilla was studied in female and male ground beetles Bembidion properans Steph. (Coleoptera, Carabidae) using scanning electron microscopy. The filiform antennae, 1.8–1.9mm in length, consist of the scape, pedicel and nine flagellomeres.
