Engineering Janus Nanofiber Interfaces for Simultaneous Triboelectric Enhancement and Wearable Comfort

Small Methods, EarlyView.
A moisture‐wicking Janus bilayer triboelectric nanogenerator (MW‐JBT) that integrates directional moisture transport with dielectric‐engineered electrospun nanofibers was developed. When incorporated into a plantar sensing system and combined with a deep learning algorithm, the MW‐JBT achieved a fall‐detection accuracy of 88.5%. This study demonstrates
