Creating a Super-Sensitive, Waterproof Strain Sensor Fabric with Graphene and Carbon Nanotubes

Have you ever thought about fabrics that can sense how your body moves? That's exactly what strain sensing fabrics do. They detect outside deformation, giving real-time feedback. The challenge? Making a fabric that's super sensitive and accurate. Scientists have now done just that with a polyurethane (PU) fabric. This material, called GCPU, is built with graphene sheets and carbon nanotubes, which form a special conductive network. This network makes GCPU highly conductive and sensitive, with a gauge factor of over 100! The fabric resists water, thanks to its hydrophobic nature, and can withstand over 1000 cycles of use. It can simulate and detect human body movements accurately. The secret? Graphene and carbon nanotubes work together to create a strong, durable fabric that's excellent for wearable technology.
