T-WiEYE: An early-age concrete strength development monitoring and miniaturized wireless impedance sensing systemT-WiEYE: An early-age concrete strength development monitoring and miniaturized wireless impedance sensing system Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-182011enThis paper develops an innovative active wireless sensing system that consists of a miniaturized electromechanical impedance measuring chip and a reusable piezoelectric transducer appropriately installed in a Teflon-based enclosure to monitor the concrete strength development at early ages and initial hydration states. To identify the degree of concrete strength evolution, electromechanical impedance (EMI) changes associated with decision boundaries based on extreme value statistics (EVS) are utilized during the hydration process. Experimental results have presented that prove the effectiveness of the proposed miniaturized sensing system to monitor concrete structures from their earliest stageshttp://creativecommons.org/licenses/by/4.0/Engineering Procedia 10484–489 Providakis Konstantinos Προβιδακης Κωνσταντινος Liarakos Evaggelos Λιαρακος Ευαγγελος Elsevier Projects, Physics physics projects projects physics Building damage prevention Building protection Buildings--Damage prevention Protection of buildings buildings protection building damage prevention building protection buildings damage prevention protection of buildings
