mi6sense is a research project that aims to revolutionize the way in which concrete structures are monitored. Smart sensors embedded within structures and foundations precisely measure relative changes in 3-D position and 3-D orientation (hence 6 degrees of freedom). The battery-free devices form a self-organizing mesh and communicate information about structural deformation from deep within the structure.
The key technological leap is the use of low frequency magneto-inductive fields which are able to penetrate concrete, soil and rock with minimal loss. This is a patent pending technique developed at the University of Oxford and which has found use in underground animal monitoring and mine rescue.
This project is being run by Dr Orfeas Kypris, a Postdoctoral Research Associate and Dr Andrew Markham, an Associate Professor in the Department of Computer Science at the University of Oxford. This project has been funded under EPSRC EP/M017583/1 from October 2014 to September 2016. The funding was awarded under a highly competitive Dragon’s Den style “big-pitch”, one of only four awards made in the area of Structural and Ground Engineering.
