Dr Robertson’s research encompasses a range of application areas for embedded electrical and electronic systems. On the small scale, his interests in micro-fabricated magnetic sensors have resulted in the development of a non-contact current probe for broadband signals in PCB tracks, groundplanes and component leads – this technology has been commercialised and is produced by TTI Ltd as the I-Prober 520. Also on the theme of sensor systems, a prototype fibre-optic probe system is currently undergoing clinical trials at Addenbrooke’s Hospital for the assessment of fat content in liver tissue – a key issue in transplant suitability of donor organs. This self-contained, compact instrument gives surgeons an instantaneous indication of tissue fat content, saving valuable time in the transplant process and optimising the use of scarce donor organs. On the larger scale, his interest in electromagnetic machines and embedded controllers is being applied to hybrid electric propulsion systems for aviation applications – in particular the simulation, modelling and development of a hybrid power plant for light aircraft, with a technology demonstrator for a parallel hybrid system currently under construction and due to commence flight testing in 2014.
