Flexible and wearable pressure sensors have attracted significant attention due to their wide range of potential applications. However, they often suffer from low sensitivity, narrow detection range, poor mechanical flexibility. In this work, a multifunctional 3D sensor based on ternary metal oxide@carbon-based sponge (C–NiCoZn–O/CMF) was developed by the hydrothermal method. The feedback layer uniformly coated with C–NiCoZn–O surface framework, which improved device's conductivity, stability significantly. sensitivities 41.99, 23.39, 11.19 kPa–1 are in ranges 0–4.01, 4.01–8.39, 8.39–20.1 kPa, respectively, cyclic retention rate exceeded 90% after 2000 cycles. C–NiCoZn–O/CMF composite demonstrated excellent electrochemical performance as an electrode for supercapacitors, high specific capacity 2030 mF/cm2 at current density 1 mA/cm2 81.55% 4000 As device, when integrated microprocessor, it can easily detect process large amount human physiological signal data daily work scenarios. Present composites maintain adjustable conductivity extremely elasticity even under extreme conditions such liquid nitrogen temperatures up 85.6 °C. This is expected play great role polar exploration, volcano survey, deep space etc.
