A nanowire assembly strategy for fabricating ultralight, resilient polypyrrole foams toward ultrasensitive pressure sensing

in the low-pressure range of 0-3 kPa and exceptional cyclic stability, enabling high-performance applications in human motion monitoring and spatial pressure analysis. This work provides an innovative structural design paradigm for CPs with a harmonious balance between ultralight characteristics and mechanical resilience, thereby opening avenues for next-generation wearable sensing platforms.
