Microfluidic Devices for Structural Health Monitoring and Integrity
Lead Research Organisation:
University of Southampton
Department Name: Faculty of Engineering & the Environment
Abstract
The proposed research will make use of world-class facilities at the University of Southampton and analytical expertise to develop advanced structural health monitoring devices capable of sensing, diagnosing and responding to damage only when necessary, leading to the construction of smart corrosion protection technology. The Southampton expertise will enable the assembly, for the first time, of an integrated device consisting of microlitre sampling, integrated advanced microfluidic and electrochemical sensing systems, wireless communications and the capability for targeted remediation (fluidic control and/or chemical inhibition) at corrosion affected areas. In addition, the device will be able to perform self-diagnostics to ensure judicious maintenance.

Description | Designs and manufacturing routes for a portable and in-situ microfluidic based capillary micro electrophoresis systems able to capture ions present in micro litres of volume of fluid extracted from crevice corrosion areas. Footprinting of ion release for a series of different crevice geometries and materials (carbon steel and NAB) were obtained using lab scale capillary electrophoresis analysis. Detection of key species and differentiation of key species (Cu2+, Ni2+, Fe3+, Fe2+, Cr3+, Mn2+, Al3+ etc) allowed footprints for active and benign crevice corrosion activity. thick film sensors were developed to detect cooper ions using screen printed platinum electrodes. |
Exploitation Route | further research using boron doped diamond electrodes has been successful In broadening the applications of electrochemical sensing of corrosion. |
