Inside Front Cover

This cover image demonstates an artificial intelligence‐enabled piezo‐yarn device developed by Kim et al. for wearable intelligent sensing. It utilizes BaTiO₃‐doped P(VDF‐TrFE) fibers, yielding remarkable shape adaptability, enhanced piezoelectric performance, and mechanical robustness. The AI yarn device enables real‐time monitoring and classification of human motion activities, achieving 99.6% accuracy using a convolutional neural network with multi‐kernel algorithms. image
