Abstract Very recently, MXene‐based wearable hydrogels have emerged as promising candidates for epidermal sensors due to their tissue‐like softness and unique electrical mechanical properties. However, it remains a challenge achieve with reliable sensing performance prolonged service life, because MXene inevitably oxidizes in water‐containing system of the hydrogels. Herein, catechol‐functionalized poly(vinyl alcohol) (PVA‐CA)‐based is proposed inhibit oxidation MXene, leading rapid self‐healing superior strain behaviors. Sufficient interaction hydrophobic catechol groups surface reduces oxidation‐accessible sites reaction water eventually suppresses hydrogel. Furthermore, PVA‐CA‐MXene hydrogel demonstrated use sensor real‐time motion monitoring, such detecting subtle human motions handwriting. The signals can be accurately classified using deep learning models.

Fiber-shaped supercapacitors (FSCs) have become one of the significantly strategical flexible energy-storage materials towards future wearable textile electronics and metaverse technologies. Here, we develop high-performance FSCs based on multiscale dot-wire-sheet heterostructure microfiber nitrogen-doped carbon dots-Ti3 C2 Tx /silk nanofibers (NCDs-Ti3 /SNFs) hybrids via microfluidic fabrication. Due to enlarged interlayer spacing, plentiful porous channels, accelerated H+ ion transport dynamics, large electrical conductivity excellent mechanical strength/flexibility, NCDs-Ti3 /SNFs possesses high volumetric capacitance (2218.7 F cm-3 ) reversible charge-discharge stability in 1 M H2 SO4 electrolyte. Furthermore, solid-state present energy density (57.9 mWh ), good (1157 long-life cycles (82.3 % retention after 40000 cycles), which realize actual energy-supply applications (powering lamp, watch toy car).

Hybrid piezoelectric/triboelectric nanogenerators combine the merits of piezoelectric (PENGs) and triboelectric (TENGs), possessing enhanced electrical output sensitivity. However, structures majority hybrid are rather complex in integrating both functions, limiting their practical application wearable electronics. Herein, we propose to construct a nanogenerator (PT-NG) with simple structure based on composite film simultaneously achieve coupling charge generation triboelectrification improved energy conversion efficiency. The consists electrospun PVDF nanofibers embedded surface PDMS film, which not only forms rough nanomorphology but also provides structural protection by during compressive deformation. results have shown that PT-NG can generate much higher outputs than individual TENG PENG devices. devices exhibit high level mechanical-to-electrical efficiency superior performance charging capacitors functioning as self-powered sensors for detection different signals from finger movement, recognition various gestures, monitoring respiration. More importantly, device possesses an impressive durability, maintaining its layered over 5000 testing cycles without noticing any obvious damage or detachment between layers. Our demonstrated combining substrate is efficient way fabricate highly harvesting intelligent identification health monitoring.
