Functionally layered sensing skin detects corrosive elements and cracking

Thursday, 24 November 2016

Researchers at North Carolina State University have developed a multi-layered "sensing skin” to detect corrosive or otherwise harmful substances in structures.

The multi-layer sensing skin is applied to a polymeric substrate with a physical crack and a reservoir for exposing the sensing skin to aggressive ions. Source:  Julie Williams Dixon/NCSU

The skin can also detect cracks and other structural flaws that are invisible to the naked eye.

Made of two layers

More specifically, the electrical impedance tomography (EIT)-based sensing skin is developed for detecting and localising the ingress of chlorides and cracking: two phenomena which are of concern in many structures, including reinforced concrete structures. The multifunctional sensing skin is made of two layers: one layer is sensitive to both chlorides and cracking, and the other layer is sensitive to cracking only. In the experiments, the sensing skin is tested on a polymeric and concrete substrate. The results demonstrate the feasibility of using the multifunctional multi-layer sensing skin for detecting and localising corrosive elements and cracking, and for distinguishing between them.

The study is published in: Structural Health Monitoring, Ocotber 6, 2016.
