Smart Joint System for In-situ Monitoring of Buildings
Chief Technology Officer
Director , Business Development
Acellent proposes to develop a smart joint structural health monitoring (SHM) sensor network that can autonomously assess in real time the structural stability of buildings. The sensor network will use piezoelectric transducers and temperature sensors to characterize damage in, and monitor the rigidity of components of the building primary structure. Acellent’s existing sensor network technology will be used as the basis for the proposed development. Phase I focused on preliminary prototyping and technology demonstrations while Phase II will focus on complete system development. Innovations in Phase II will include development of a SmartDAQ sensor package that includes the piezoelectric transducers, temperature sensors, hardware, energy harvested power, battery, wireless data transmission and intelligent software. This will be used to provide a real time assessment of the building structural integrity. The data will be available for display to provide and early warning to first response and emergency personnel to ensure their safety prior to entering the building. An additional development will be to use the sensors to recognize sound and/or voice transmitted through the structure to allow search and rescue personnel to pinpoint the location of survivors and determine what they are trying to say through an easy conversion to text messaging.
