In 2000 Plastic Logic, a Cambridge-based start-up company, announced it was attempting to commercialise a form of plastic electronics that had developed from research at the laboratory. By using a cheap and simple set of processing operations to build up layers of circuitry on plastic “substrates” – the material on which circuits are formed – rather than silicon wafers used in conventional microchips, the developments promised to slash the cost of making semiconductors. What has given the science behind the company more substance is today’s announcement that Plastic Logic has attracted $100m (£51m) of investment that will fund a plant...
