Short summary
We describe a low-cost sensor for the detection of ethanol in alcoholic beverages. The reversible swelling of alcohol-sensitive hydrogels depends on the ethanol concentration. The resulting swelling pressure was detected via piezoresistive sensors. We have tested the swelling properties of the hydrogel (e.g. swelling kinetics, selectivity to other alcohols). Furthermore, the first sensor set-ups were tested and the reversibility of the hydrogel-based piezoresistive sensor was demonstrated.
