Abstract
A device for detecting at least one substance may include a resonator which, on its surface facing away from the carrier, is provided with a chemically sensitive layer for selectively binding a substance that is to be detected. An acoustic mirror is arranged between the carrier and the resonator. The acoustic mirror constitutes a band elimination filter having two closely adjacent notch frequencies, as a result of which the device is capable of oscillating in two resonant frequencies. The mass binding of the substance and the temperature can be determined computationally from the measured resonant frequencies.
