Are there fabrics that change color based on soil moisture levels?

Yes, there are innovative fabrics designed to change color in response to soil moisture levels. These smart textiles incorporate moisture-sensitive materials or chemical indicators that react to water content in the soil, shifting hues to visually signal hydration changes. Such fabrics are particularly valuable in agriculture, where they can serve as real-time moisture detectors for crops, reducing water waste and improving irrigation efficiency. Advanced versions may even integrate nanotechnology or photonic crystals for more precise and vibrant color transitions. While still in development, these fabrics represent a promising intersection of textile engineering and environmental monitoring, with potential applications ranging from farming to wearable sensors. Researchers continue to refine their sensitivity and durability for broader commercial use.
