Abstract: A capsule includes a deformable and/or compressible casing, provided with a base wall and a side wall defining a cavity that is open and suitable for containing an initial product to obtain a final food product. A supporting element is fixed to a first edge of the casing and facing the cavity and a nozzle is fixed to the supporting element and arranged for delivering a fluid into the cavity which interacts with the initial product to make the final product. The nozzle also opens the base wall and enables the final product to exit when the casing is compressed and crushed.

Abstract: A MEMS acoustic transducer has: a detection structure, which generates an electrical detection quantity as a function of a detected acoustic signal; and an electronic interface circuit, which is operatively coupled to the detection structure and generates an electrical output quantity as a function of the electrical detection quantity.

Abstract: A MEMS acoustic transducer device has a capacitive microelectromechanical sensing structure and a biasing circuit. The biasing circuit includes a voltage-boosting circuit that supplies a boosted voltage on an output terminal, and a high-impedance insulating circuit element set between the output terminal and a terminal of the sensing structure, which defines a first high-impedance node associated with the insulating circuit element. The biasing circuit has: a pre-charge stage that generates a first pre-charge voltage on a first output thereof, as a function of, and distinct from, the boosted voltage; and a first switch element set between the first output and the first high-impedance node. The first switch element is operable for selectively connecting the first high-impedance node to the first output, during a phase of start-up of the biasing circuit, for biasing the first high-impedance node to the first pre-charge voltage.
