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 8):
The screw according to  claim 1 , wherein the power supply comprises:\n a first power supply element connected to the coil to receive a first supply current and connected to the microprocessor to power the microprocessor; a second power supply element connected to the coil to receive a second supply current, distinct from the first supply current, and connected to the coil through a changeover switch acting in conjunction with the second power supply element to define the transmitter, to transmit to the coil a transmission current which is variable according to a curve representing the measurement parameter measured, in order to generate the wireless measurement signal by electromagnetic induction through the coil, wherein the microprocessor is connected to the changeover switch to drive the changeover switch through a drive signal.
