Abstract Laser‐induced graphene (LIG) technology has provided a new manufacturing strategy for the rapid and scalable assembling of triboelectric nanogenerators (TENG). However, current LIG‐based TENG commonly rely on polymer films, e.g., polyimide (PI) as both friction material carbon precursor electrodes, which limit structural diversity performance escalation due to its incapability folding creasing. Using specialized PI paper composed randomly distributed fibers substantially enhance foldability, this work creates type TENG, are structurally foldable stackable, tailorable. First, by systematically investigating laser power‐regulated single‐unit open‐circuit voltage can be effectively improved. By further exploiting process, multiple units assembled together form multi‐layered structures continuously expand from 5.3 34.4 V cm −2 , increase 1 16. Last, fully utilizing unique structure performance, representative energy‐harvesting smart‐sensing applications demonstrated, including smart shoe recognize running motions power LEDs, leaf thermometer wind, matrix sensor writing trajectories, well glove different objects.

Emulating biological perception mechanisms to construct intelligent sensing devices and systems represents a paradigm for promoting human–computer interaction in the Internet of Everything era. Nonetheless, developing highly sensitive, real-time rapidly integrated units remains challenging time-consuming endeavor. This study employs low-temperature glow discharge technique fabricate graded nanotexturing architectural triboelectric nanopaper, upon which wearable sensors tactile detection are designed. The structure enhances contact area under an external force. Additionally, Z-stacking design enables sensor achieve remarkable sensitivity 10.3 kPa–1 rapid response time 52 ms. Furthermore, array was designed demonstrate sensor's ability recognize characteristic pressures. With programmable machine learning techniques, object recognition rate reached 97%. supports material structural across disciplines, laying solid foundation fabrication integration transient electronics.
