Our main research interest is to develop novel infrared and electronic sensing technologies for skin measurements and industrial Non-Destructive Testing. With funding from EPSRC, Royal Society, and various industries, work has been done on skin hydration and hydration depth profiling, skin thickness, skin pigments, transdermal drug delivery, membrane permeation, nail and hair measurements, instrument performances and thermal diffusivity effects, by using photo-thermal radiometry technology. We also work on skin Trans-Epidermal Water Loss (TEWL) measurements and capacitive imaging based on Fingerprint sensors.

Through Biox Systems Ltd, our university spin-out company, we have commercialised two measurement technologies, AquaFlux and Epsilon. AquaFlux is a patented, novel, condenser-chamber instrument for TEWL measurements, and Epsilon is a capacitance fringing field instrument for permittivity imaging of soft materials. AquaFlux and Epsilon have been sold to over 70 organisations worldwide, including universities, hospitals and leading international cosmetic companies such as Unilever, P&G, L'Oreal, and Johnson & Johnson etc.
