WIRELESS IC TAG, AND SYSTEM FOR MANAGING QUALITIES OF CONCRETE STRUCTURE USING THE WIRELESS IC TAG

WIPO Patent Application WO/2010/146726

A1

Provided is a wireless IC tag which monitors the temperature, hydrogen-ion exponent and strain of a concrete structure. In a wireless IC tag (1) which is attached to or embedded in a concrete structure (11), ferroelectric memory, which uses a ferroelectric having a power supply section which receives radio waves from the outside and generates a current by resonating with the radio waves and an antenna section which performs wireless communication in a predetermined frequency band, a temperature sensor (4), a Ph sensor (5) and a strain sensor (6) are mounted on a substrate (2). At least one kind of data selected from among the temperature data of the structure measured by means of the temperature sensor (2), the hydrogen-ion exponent data of the structure measured by means of the Ph sensor (5), and the strain data of the structure measured by means of the strain sensor (6) is stored in the ferroelectric memory.
