The STFC Innovations Club hosted an event on Novel magnetic sensors and their applications. The workshop addressed the following type of sensors and their applications:

  • Quantum Well Hall Effect (QWHE) sensors
  • Portable SQUID magnetometers
  • Fluxgate magnetometers
  • Characterisation tools for functional magnetic materials

The sensors based on advanced Quantum Well Hall Effect (QWHE) display unprecedented sensitivity and dynamic range ( > 180dB) allowing magnetic fields down to 1nT to be measured in an active volume of less than 0.001 mm3.

  • These sensors support 2D planar and conformal array geometries on rigid and flexible substrates which opens possibilities not possible with induction techniques.
  • There also have advantages in integrated circuits, mass production, repeatability, low power consumption, ease of use and lower costs.

A SQUID (superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops containing Josephson junctions. SQUIDs are sensitive enough to measure fields as low as 5 aT (5×10-18 T) and reach a noise level of ~fTHz-1/2.
Applications of magnetic sensors

    • High-accuracy magnetometry, long-range position sensing, angular position sensing, current sensing, magnetic scanning of documents
    • Non Destructive Testing (NDT), monitoring asset integrity, use of radiation hard camera for nuclear industry
    • Magnetic near-field communications and sensing, the markets span oil & gas, defence and niche custom applications with products in low data-rate underwater communications, data logging, sensing and induction power transfer
    • Extremely low magnetic fields detection (e.g. detection of underground water level and its salinity).

This workshop aimed to pull together the interest from both the academia and industry in order to facilitate knowledge exchange (KE) between STFC funded researchers working in the area of magnetic materials and sensors and industry with a view to exploiting synergies between academic research and industry. 
The workshop further highlighted funding opportunities to support KE relationships around novel magnetic sensors and materials as well as provide an opportunity to hear a general update on their development and possible applications.
