It has been known for years that dogs can detect disease, but a Welsh semiconductor company says that optical sensors in healthcare devices for the home could one dayprovide a similar early warning system.
IQE of St Mellons, Cardiff, makes compound semiconductors composed of two or more chemical elements. These work faster than conventional, single-element silicon semiconductors. The wafers that are the base for semiconductors can be found in mobile phone handsets and are also used in lasers. They were a key technology in DVD and Blu-ray players.
