Cambridge scientists create a $10 chip that could put a medical lab on your wrist

Cambridge researchers have created a groundbreaking $10 optical sensor that delivers the precision of laboratory equipment in a device small enough for wearable technology. It identified foods, plastics, and medicines with 100% accuracy in tests and demonstrated the ability to monitor blood glucose, alcohol, and other health markers without invasive procedures.

The technology could also transform food testing, industrial quality control, and environmental monitoring. Researchers at the University of Cambridge and GlitterinTech (a start-up founded by the same research group) have developed a new type of optical spectrometer that combines exceptional accuracy with a remarkably small size and low cost. Measuring just centimeters across, the device could be incorporated into portable electronics and wearable health technology.

Its potential applications range from monitoring important health markers in real time to identifying materials and detecting changes in chemical composition. Optical spectrometers work by analyzing light to reveal information about the substances it interacts with. They are essential tools in medicine, manufacturing, chemical testing, and environmental research.
