All-biomass flexible sensor based on lignin carbon nanospheres/cellulose for human motion detection.

Summary: Scientists have created a new, bendy sensor made entirely from plant materials like wood and leaves (lignin and cellulose). This "all-biomass" sensor sticks well to human skin and can track how our bodies move. It is very fast, reacting in just a fraction of a second (0.3 seconds), and it keeps working perfectly even after being bent over 5,000 times! It can also feel a wide range of pressure, making it a great, eco-friendly tool for future wearable tech and health tracking.
