Abstract

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.
