Pyreos is the world’s only volume supplier of thin-film PZT pyroelectric sensors. The company develops and makes these infra-red sensors for use in a wide variety of industrial and consumer products ranging from devices that detect flames or analyse gases through to spectrometers which analyse foodstuffs, engine oils and blood, through to switches and other electronics that detect gestures and presence. The company was spun out from German multinational Siemens in 2007 following €10m (£7.5m) of research and development work and is based at the Scottish Microelectronics Centre on the University of Edinburgh’s Kings Buildings campus. Investors are Siemens Technology Accelerator (STA), Robert Bosch Venture Capital GmbH (RBVC), Scottish Investment Bank (the investment arm of Scottish Enterprise), Strathtay Ventures (a subsidiary of Braveheart) and Seraphim Capital.
