Researchers are pioneering new sensor and imaging technologies with applications across medicine and environmental monitoring. A perovskite-based image sensor developed by ETH Zurich and Empa demonstrates superior low-light performance and color fidelity by vertically stacking color-specific layers, surpassing conventional silicon-based sensors. A compact quantum magnetometer using nitrogen vacancy diamonds from Fraunhofer Institute offers high sensitivity nano-scale magnetic field measurement ideal for biomedical and navigation uses. Advances in crystalline silicon meta-optics have enabled full-color visible light imaging with thinner, more efficient optics. These breakthroughs may catalyze next-generation devices in diagnostics, environmental sensing, and optical computing.
