[摘要]：Strain gauges for non-destructive testing could successfully deposited by INKtelligent printing (R). Metal strain gauges are fabricated by Aerosol Jet (R) technology, starting with deposition of a polymer isolation layer, followed by a printed metal layer and finally an encapsulation to protect the printed sensor. Characterizations of printed and sintered sensors show a good densification of the printed material which allows high electrical conductivity up to 70% of bulk value. Performance tests of printed sensors show a reproducible and reliable functionality in terms of strain measurements. (C) 2010 Elsevier B.V. All rights reserved. |
