Abstract

A measuring device for determining a gas concentration includes a gas-sensitive element, a sensing device, a stimulation unit, and a processing unit. The gas-sensitive element is configured to absorb a gas. The sensing device is configured to determine a parameter of the gas-sensitive element in a predetermined time period, where the parameter depends on an absorbed quantity of the gas. The stimulation unit is configured to stimulate the gas-sensitive element and accelerate desorption of the gas out of the gas-sensitive element. The processing unit is configured to determine a rate of change of the parameter, to control the stimulation such that a concentration of the gas in the gas-sensitive element lies outside of an equilibrium state, and to determine the gas concentration based on the rate of change.
