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 10):
A wireless system for reading a tightening force of a screw applied to a structure, comprising:\n an extensometer connected to a shank of the screw, configured to measure a measurement parameter representing a tightening force of the screw; a coil, a power supply, a microprocessor and a transmitter, all located in a housing made in the screw, wherein the power supply is connected to the coil, to receive electrical energy and to the microprocessor and the extensometer to supply the coil and the microprocessor with electric power, and wherein the microprocessor is connected to the extensometer to receive the measurement parameter measured by the extensometer and is connected to the transmitter to transmit the measurement parameter externally of the screw through a wireless measurement signal; and a reading device having a receiver, an electrical energy source, a processor and a winding, wherein the processor is programmed to generate a primary supply current in the winding to generate a magnetic field and induce a secondary supply current in the coil of the screw, thereby transmitting electrical energy to the power supply of the screw through a contactless transmission line, and wherein the receiver is configured to detect the wireless measurement signal generated by the microprocessor of the screw and the processor of the reading device is programmed to process the wireless measurement signal to acquire the measurement parameter.
