Abstract:
Provided is a screw that includes a threaded shank extending along a longitudinal axis; a head configured to be engaged by a tightening tool to tighten the screw; and an extensometer housed in a longitudinal cavity made in the shank, to measure a measurement parameter representing a tightening force of the screw. A coil, a power supply, a microprocessor and a transmitter are located in a housing made in the head. The power supply is connected to the coil to receive electrical energy by electromagnetic induction through a contactless transmission line, and to the microprocessor and extensometer to supply them with electric power. The microprocessor is connected through a conditioning module to the extensometer to receive the measurement parameter and to the transmitter to transmit the measurement parameter externally of the screw through a wireless measurement signal.

Claim (Index 11):
A method for reading a tightening force of a screw applied to a structure, comprising:\n measuring a measurement parameter representing a tightening force of the screw, by means of an extensometer connected to a shank of the screw; preparing a reading device having a receiver, an electrical energy source, a processor and a winding; preparing, in a housing made in the screw, a coil, a power supply, a microprocessor and a transmitter; moving the reading device close to the screw until the winding of the reading device is magnetically coupled to the coil of the screw; electrically energizing the power supply and the microprocessor of the screw, by transmitting electrical energy from the reading device through the contactless transmission line defined by the winding of the reading device magnetically coupled to the coil of the screw; acquiring, by means of the microprocessor of the screw, the measurement parameter measured by the extensometer; transmitting the measurement parameter to the receiver of the reading device through a wireless measurement signal by the transmitter of the screw driven by the microprocessor; processing the wireless measurement signal by means of the processor of the reading device in order to acquire the measurement parameter.
