Kent’s research on biometrics – the identification of individuals through their physiological or behavioural characteristics – has led to significant developments within industry. At present, analysing the unique patterning of the iris within the human eye is one of the most popular methods in use.
Research at Kent, in collaboration with British company Smart Sensors, has developed new ways to improve iris recognition systems, overcoming previous constraints such as the need to direct the gaze straight at the camera. The approach developed at Kent is flexible enough to deal with multiple gaze angles in varying light conditions.
The team has also worked on areas such as handwriting and signature recognition, as well as facial recognition. Michael Fairhurst has been influential in the wider debate on the use of biometrics, advising the UK Government on the technology for biometrics, as well as related ethical and privacy issues.

Wi-Fi connectivity and mobile phone coverage can be problematic in buildings with signal blockage and interference. Research at Kent has tackled this problem with the design of antennae and frequency selective surfaces (FSS) that can be intimately integrated into buildings.
Kent has also developed antennae for vehicles. Collaboration with Harada Europe led to integrated antennae that take advantage of roof panels, boot lids and bumper mouldings. More recently, work on skin-mounted antennae led to printed transfer tattoos of radio-frequency identification tags. Such tags can be used for security and ticketing, or for hospital patients, to ensure their medical regimes are followed.
Reducing carbon emissions

New technology developed at Kent could play a major role in the global challenge of tackling climate change. It was used to help Drax, the largest power station in the UK, move from firing coal to a combination of biomass and coal, as it sought to halve its carbon footprint within five years.
Based on new instrumentation, the technology allows the engineers to diagnose the combustion process and optimise the operation of coal, biomass and heavy-oil-fired power plants. It has been applied in countries including the UK, France, China and Saudi Arabia, and is likely to have the greatest impact in countries such as China, where up to 70% of energy is generated from coal-fired power plants.
