Silver nanowire-based transparent electrodes
In collaboration with the University of Sussex and an industrial partner, we developed silver nanowire (AgNW) transparent electrodes specifically tailored for flexible touch screen applications. We fabricated for the first time a fully operating five inch multi-touch highly-pixelated AgNW sensor with comparable performance to one based on ITO typically used in smart phone technology. We also showed that the finite-size scaling theory can be successfully applied for the fundamental understanding of touch sensors performance of where highly pixelated sensor structures are essentials such as in single-layer capacitive touch sensors but also in LCD and OLED display panels. The work has been featured on the University of Surrey website and in national news-papers, such as the Daily Mail and Daily Express, as well as multiple digital outlets (IEEE Spectrum, Phys.org, etc).
Silver nanowire/graphene hybrids for cheap and flexible touch screen applications
Recognising the need for finding cheaper alternative to Indium Tin Oxide (ITO) electrodes currently used for touch screen applications, we have also developed graphene/silver nanowire hybrid transparent electrodes. It can serve as a cheap replacement for expensive and scarce Indium. We have shown that out approach enables to reduce the amount of nanowires needed to produce viable transparent electrodes more than fifty times than the equivalent pristine high density nanowire networks; thus having major commercial implications.The research was featured on the University of Surrey website and on over 20 science-related websites internationally including forbes.com, phys.org, electronicsweekly.com and sciencedaily. com.
