Bridge expansion joint monitoring

MagniGap sensors can be attached to either side of the expansion gap on a bridge, to monitor relative position between opposing joints in 3-D, as well as structural vibrations.

Position sensing for DFMA

MagniGap sensors work even through concrete, and can be embedded in pre-manufactured concrete blocks to guide assembly, in 3-D.

Crack monitoring

MagniGap sensors can be embedded in concrete or attached after construction to monitor crack width over time, in 3-D.

The Vision

The Structalyse project aims to revolutionize the way valuable structures are monitored by combining the following two strengths:

  1. A low-cost, patent-pending sensor (MagniGap) developed at the University of Oxford, which uses a unique fusion of sensing modalities to measure 3-D displacement and orientation between a pair of sensors, as well as moisture, temperature and other environmental variables, without wires, without moving parts, and without the use of line-of-sight technology.
  2. Advanced analytics algorithms that use data collected from deployed MagniGap sensors to create meaningful condition indicators for the effective evaluation of structural condition.

This project is an offshoot of, and the first step towards realising the mi6sense project - check it out!
