The flexible pressure sensor has attracted much attention due to its wearable and conformal advantage. All the same, enhancing electrical structural properties is still a huge challenge. Herein, integrated (FIPS) composed of solid silicone rubber matrix, composited with piezoelectric powers polyacrylonitrile/Polyvinylidene fluoride (PAN/PVDF) conductive silver-coated glass microspheres first proposed. Specifically, mass ratio PAN/PVDF up 4:5 after mechanical mixing. output voltage composite...
Abstract The combination of fluidity and metallic conductivity has attracted considerable attention to liquid metal (LM), but its development remains challenging due enormous surface tension. Here, vinyl‐terminated silicone oil platinum catalyst are added LM reduce tension, which develops a special type liquid‐metal‐silicone (LMS) ink with diffusion effect. Combined an embedded three‐dimentional (3D) printing method, the LMS is printed on support matrix, diffuses outward along print path...
Abstract Traditional accelerometers rely on batteries to provide energy, and the massive use of caused great pressure natural environment. In this paper, a self‐powered acceleration sensor is designed. To more easily harvest weak vibration signals effectively improve sensitivity, built magnetic levitation type double helix structure ZnO‐doped triboelectric film. Experiments indicated that open‐circuit voltage short circuit current nanogenerator (TENG) doped with ZnO are increased by 2.51...
Abstract The uneven time‐space distribution of rainfall can easily induce droughts and floods disasters. Meteorological sensor based on battery supply plays an important role to monitor warn intensity, however it is limited by the frequent replacement battery. In this paper, a dual mode self‐powered (DSR‐Sensor) hybrid enhanced triboelectric nanogenerator (TENG) first proposed. DSR‐Sensor fabricated with frictional layer polydimethylsiloxane (PDMS) electrode Cu. These layers are assembled...
Human–machine interaction is now deeply integrated into our daily lives. However, the rigidity and high-power supply of traditional devices limit their further development. Herein, a high-performance flexible piezoelectric sensor (HFPS) based on novel zinc oxide/polyacrylonitrile/Ecoflex (ZnO/PAN/Ecoflex) composite membrane proposed. Due to synergistic piezoelectricity ZnO PAN, output voltage/current HFPS increased by 140%/100% compared pure Zno/Ecoflex membrane. Furthermore, fabricated...
The self-driven sensor based on contact-separation type triboelectric nanogenerator (CS-TENG) has garnered significant attention due to its excellent compatibility with human gait characteristics at low frequencies. Conventional CS-TENGs transfer charge between two heterogeneous friction materials through passive separation caused by external forces. This article presents a novel design of an elastomeric driven structure as carrier for the CS-TENG, aiming mitigating hysteresis and enhancing...
Abstract Triboelectric nanogenerators are characterized by zero power consumption and often employed as self-powered sensors. However, the complex manufacturing process expensive equipment limit further promotion application of sensors, which have become urgent challenges in this field. Here, a simple strategy using embedded three-dimensional (EMB 3D) printing is proposed to enable fabrication diverse sensors one-step, reducing production costs while increasing design flexibility....
