METHOD AND SYSTEM FOR DISTRIBUTED NETWORK OF NANOPARTICLE INK BASED PIEZOELECTRIC SENSORS FOR STRUCTURAL HEALTH MONITORING

摘要

PROBLEM TO BE SOLVED: To provide a method and system for structural health monitoring based on nanoparticle sensors disposed on a surface of a structure.

SOLUTION: A system 170 for monitoring structural health 172 of a structure 30 has a distributed network 120 of nanoparticle ink based piezoelectric sensor assemblies deposited onto the structure 30. Each assembly has a plurality of nanoparticle ink based piezoelectric sensors 110 and a plurality of conductive ink power and communication wire assemblies 140 interconnecting the plurality of sensors 110. The system further has an ink deposition apparatus 142 depositing the distributed network of nanoparticle ink based piezoelectric sensor assemblies onto the structure 30. The system further has an electrical power source 178 providing electrical power to the distributed network 120. The system further has a data communications network 179 retrieving and processing structural health data 174 of the structure via one or more signals from the sensors 110.
