Abstract
A vapor and/or gas concentration and temperature sensor includes a resonating structure having a first side with a functionalized surface and a second side opposite the first side, a first resonant frequency of a first vibration mode, and a second resonating frequency of a second vibration mode. Drive and sensing electrodes face the second side of the resonating structure. A direct current bias source is coupled to the resonating structure. A first AC voltage source provides the resonating structure with a first voltage having a frequency corresponding to the first resonant frequency. A second AC voltage source provides the resonating structure with a second voltage having a frequency corresponding to the second resonant frequency. A read-out circuit determines a vapor and/or gas concentration based on a difference between the frequency of the first voltage and a first read-out frequency and determines a temperature based on a difference between the frequency of the second voltage and a second read-out frequency.
