High-Performance Textile-Based Capacitive Strain Sensors via Enhanced Vapor Phase Polymerization of Pyrrole and Their Application to Machine Learning-Assisted Hand Gesture Recognition

High-Performance Textile-Based Capacitive Strain Sensors

In article number 2400292, Alexander Shokurov, Carlo Menon, and co-workers present high-performance textile-based capacitive strain sensors for wearable applications. Through vapor-phase polymerization of pyrrole, enhanced via addition of co-vapor and imidazole, good conductivity and robustness are achieved in a stretchable textile. A new insulation technique using polymer composites provides durability and dielectric coating. Intertwining such fibers together creates a stretchable capacitive sensor. Integrated into a textile glove, sensors precisely capture fine hand motions. A machine learning model classifies 12 gestures with 100% accuracy, showcasing its potential for wearable technology.
