WIRELESS IC TAG, CONCRETE STRUCTURAL OBJECT QUALITY MANAGEMENT SYSTEM USING SAME

摘要

A wireless IC tag 1 attached to or embedded in a concrete structural object 11 including a ferroelectric memory using a ferroelectric having a power source unit for receiving a radio wave from outside and for generating an electric current by resonating with the radio wave and an antenna unit for carrying out wireless communication in a predetermined frequency bandwidth, a temperature sensor 4, a Ph sensor 5, and a distortion sensor 6 which are mounted on a substrate 2. At least any one of temperature data of the structural object measured by the temperature sensor 4, hydrogen-ion exponent data of the structural object measured by the Ph sensor 5, and distortion data of the structural object measured by the distortion sensor 6 is saved in the ferroelectric memory.
