Researchers are exploring the possibility of using the skin as a health monitor, with some developments suggesting that skin could glow to signal inflammation or other health issues. A "living sensor display" that turns skin into a health monitor has been developed, and a glowing skin patch is being studied as a potential warning system for health problems. The technology's potential applications and current stage of development are not entirely clear, with some reports focusing on its future possibilities and others discussing related but distinct areas of medical research.
