DEVICE FOR DETECTING STRAINS AND TRANSMITTING DETECTED DATA AND METHOD FOR MANUFACTURING THE SAME

摘要

A device for detecting strain and transmitting detected data, as well as a method for the manufacturing of a device of the type indicated above are provided. The device can be either applied to the surface of a structure to be monitored or inserted inside the structure and it allows to reliably acquire and transmit the data relating to the strains suffered by the structure, avoiding errors due to disturbances in the positioning of the strain sensor of the device or in the electronics associated with the sensor. The device includes a middle layer, in which at least one strain sensor made by using a composite material containing electrically conductive impregnable fibers, an electronic circuit and at least an antenna are provided, and a first and a second outer layers made by using a composite material containing electrically insulating impregnable fibers, between which the middle layer is placed.
