A method for activating a gas, wherein an electrically conductive aeromaterial having a pore space comprising the gas is electrically contacted and at least one electric current, which varies over time, flows through the aeromaterial, wherein the aeromaterial exhales gas from the pore space when the electrical power consumption is increased and inhales gas from the surroundings of the aeromaterial when the power consumption is decreased, and wherein a temporally pulsed current having predefined pulse power levels, pulse durations and pulse spacings is fed through the aeromaterial and the temperature of the aeromaterial is changed by the time-varying current by 100° C. or more within one second or less. The invention also relates to an electrothermal gas actuator and to uses of a gas actuator.

Method for producing metallic surface discharge electrodes on nonmetallic substrates comprising the following steps: a) producing a metallic seed layer on a substrate; b) electrically contacting the seed layer with a metal wire network and an electrolyte containing metal ions; c) electrodepositing a metal film from the electrolyte at least on the seed layer, with the metal wire network being embedded into the metal film, wherein d) metal wire filaments that are movable relative to one another are arranged to form an electrically percolating metal wire network, e) the arrangement of the metal wire filaments is cast into a gel and the gel is dried thereafter to the gel matrix, and f) the dried gel matrix with the metal wire network embedded therein is applied to the substrate and is wetted with a solvent of the gel matrix. Furthermore, the invention relates to a semifinished product for carrying out the method.
