    Abstract: An electronic microbalance (1) made in a semiconductor body (2) accommodating an oscillating circuit (38) adjacent to a diaphragm (18; 121;151). A stack formed by a first electrode (10), a second electrode (15), and a piezoelectric region (11) arranged between the first and the second electrode extends above the diaphragm. Any substance that deposits on the stack causes a change in the mass of the microbalance and thus in the resonance frequency of a resonator formed by the microbalance and the oscillator (19) connectable thereto and can thus be detected electronically. A chemical sensor is obtained by forming a sensitive layer (16) of a material suitable for binding to target chemicals on the stack.
