    Abstract: An electrostatic micromotor (10') is provided with a fixed substrate (12), a mobile substrate (13) facing the fixed substrate (12), and electrostatic-interaction elements (14, 15, 17) enabling a relative movement of the mobile substrate (3) with respect to the fixed substrate (2) in a movement direction (x); the electrostatic micromotor is also provided with a capacitive position-sensing structure (18') configured to enable sensing of a relative position of the mobile substrate (13) with respect to the fixed substrate (12) in the movement direction (x). The capacitive position-sensing structure (18') is formed by at least one sensing indentation (22), extending within the mobile substrate (13) from a first surface (13a; 13b) thereof, and by at least one first sensing electrode (24), facing, in at least one given operating condition, the sensing indentation (22).

    Abstract: Device (100) for detecting and monitoring local parameters within a solid structure (300). The device comprises an integrated detection module (1) made on a single chip, having an integrated functional circuitry portion (16) comprising at least one integrated sensor (10) and an integrated antenna (11), and electromagnetic means (2) for transmitting/receiving signals and energy exchange. The integrated functional circuitry portion (16) comprises a functional surface (18) facing towards the outside of the chip. A passivation layer (15) is arranged to completely cover at least the functional surface (18), so that the integrated detection module (1) is entirely hermetically sealed and galvanically insulated from the surrounding environment. The integrated antenna (11), the electromagnetic means (2) and the remote antenna (221) are operatively connected wirelessly through magnetic or electromagnetic coupling.
