Claim 5:
6. The MEMS device according to claim 1, wherein the first gas sensor comprises:
a first heater element, which extends over a second buried cavity in the one of the first semiconductor body or the second semiconductor body at the respective first surface, and is configured to generate heat when biased;
an electrically insulating layer, extending on the first heater element; and
a gas-detection unit including:
a first plate and a second plate extending over the electrically insulating layer, the first plate and the second plate configured to be capacitively coupled together; and
a gas-adhesion layer extending over the first and second plates, facing the first duct, and configured to adhere the gas.
