Metal‐Organic Framework Reinforced Highly Stretchable and Durable Conductive Hydrogel‐Based Triboelectric Nanogenerator for Biomotion Sensing and Wearable Human‐Machine Interfaces

Flexible triboelectric nanogenerators (TENGs) with multifunctional sensing capabilities offer an elegant solution to address the growing energy supply challenges for wearable smart electronics. Herein, a highly stretchable and durable electrode TENG is developed using ZIF-8 as reinforcing nanofiller in hydrogel LiCl electrolyte. nanocrystals improve hydrogel's mechanical properties by forming hydrogen bonds copolymer chains, resulting 2.7 times greater stretchability than pure hydrogel. The encapsulated microstructured silicone layers that act materials prevent water loss from Optimized ZIF-8-based electrodes enhance output performance of through dynamic balance electric double (EDLs) during contact electrification. Thus, as-fabricated delivers excellent power density 3.47 Wm–2, which 3.2 higher hydrogel-based TENG. can scavenge biomechanical even at subzero temperatures small electronics serve self-powered pressure sensors human-machine interfaces (HMIs). nanocomposite also function biomotion sensor, detecting body movements high sensitivity. This study demonstrates significant potential utilizing reinforced TENGs harvesting sensor technology.
