New sensor offers potential for low-cost medical imaging

UK researchers have developed a new type of light sensor that could allow medical imaging to be carried out using low-cost cameras.

The University of Surrey team have created a new sensor that detects the full spectrum of light – from ultraviolet to visible and near-infrared light – while remaining highly flexible and cheap to produce.

Its near-infrared light capabilities could be used to perform non-invasive medical procedures, such as measuring the oxygen level in tissue and detecting tumours, while the devices are also capable of capturing high-quality images in the dark.

The sensors can be produced using the same laser printers found in homes and offices and, unlike other similar sensors, do not require specialised manufacturing conditions.

Lead researcher Dr Richard Curry, from the University of Surrey's Advanced Technology Institute, said this technology "may eventually enable parents to simply monitor a child's blood or tissue oxygenation level via a smartphone camera that could be linked to healthcare professionals".

Dr Curry is a recognised expert in the field of imaging systems and light-emitting devices.
