Consultancy and Research & Development

Application Areas

R&D: Research and development is the origin of many new and novel products, such as transducers, fuel cells, scleral lenses and restorative surgery aids. Project partners include Moorefield Eye Hospital and universites of Oxford, Surrey and Cranfield in the UK and Lehigh University in the USA.
