Novel measurement techniques have been developed to characterise the mechanical and electromagnetic properties of materials
Conductivity and permeability can be linked to the state of stress and strain in a metal and used to assess its integrity. These can provide information about the microstructure of the material and can be used to detect damage precursors. Therefore, enabling the possibility of detecting damage before it occurs.
Current Electromagnetic Projects:
We have developed a series of ‘dipstick’ sensors that can be simply immersed into fluids in order to analyse properties such as viscosity or fluid bulk velocity. The simple geometry of the waveguides (‘dipsticks’) makes these devices ideal for online-monitoring applications. Dipstick sensors are also used to monitor the elastic moduli during the cure of adhesive joints in automotive components as well as the curing of concrete.
