Rapid Biosensor Systems Ltd, a Cambridge-based technology and business development company, innovates and exploits technology solutions for the rapid detection of infectious diseases at the point-of-care. The first target disease was Tuberculosis and the company required an industrial design solution that met a demanding product requirement specification. Design Edge helped RBS to give birth to the TB Breathalyser which requires the non-invasive collection and testing of cough samples, whilst ensuring that the system is portable, simple to use, low cost, rapid and safe. It is vital that it can be used in the Third world. Design Edge have been working with RBS throughout all the product development phases from initial concepts right through to pre-production design which was proven to be extremely accurate in field trials in India and Africa.
