Cambridge Team Unveils $10 Optical Sensor for Non-Invasive Health Monitoring
University of Cambridge researchers have developed a low-cost optical spectrometer that achieves laboratory-grade precision in a miniature form factor. The device, which costs approximately $10 to produce, utilizes a novel convolutional approach to analyze light, enabling accurate identification of materials and non-invasive monitoring of biological markers. Tests demonstrated 100% accuracy in classifying various substances and the ability to track blood glucose without needles. The technology is designed to be integrated into wearable devices, potentially revolutionizing personal health monitoring, industrial quality control, and environmental analysis by making sophisticated spectral analysis accessible and affordable.
