Flexible pressure sensors and aqueous batteries have been widely used in the rapid development of wearable electronics. The synergistic functionalities versatile materials with multidimensional architectures are recognized to a significant impact on performance flexible Herein, facile hydrothermal strategy was demonstrated conformally grow vanadium dioxide nanosheets carbonized cotton fabrics (VO2/CCotton), which is candidate material piezoresistive sensors. As result, VO2/CCotton-based sensor behaved high sensitivity (S = 7.12 kPa-1 range 0-2.0 kPa) stable sensing ability wide scale 0-120 kPa. Further practical applications were performed monitoring delicate physiological signals as well, such twisting, blowing, voice vibration recognitions. In addition, another application for energy storage investigated well. A quasi-solid-state zinc-ion battery assembled VO2/CCotton cathode film Zn nanosheets/carbon nanotube anode. capacity 301.5 mAh g-1 remarkable durability 88.7% retention after 5000 cycles at 10 found. These exceptional outcomes attributed unique three-dimensional architecture prominent synergetic effects CCotton VO2 allow proposal novel guidelines next-generation multifunctional
