The electricity generation of triboelectric nanogenerators (TENGs) originates from charge transfer enabled by contact electrification. However, the inherent barrier between two contacting surfaces hampers transfer. There are mainly four ways to promote triboelectrification TENGs. While synergy among them has never been achieved. Herein, we reported an effective strategy boost efficiency synergizing strong ferroelectric polarization and high permittivity embedded lead zirconate titanate fillers. influence interfacial intensity dielectric permittivity, as well corona poling, on composite film was systematically investigated. Notably, switching direction renders increase (207%) or a decrease (71%) in output comparison with non-poled counterpart.

Abstract The simultaneous detection of multiple stimuli, such as pressure and temperature, has long been a persistent challenge for developing electronic skin (e‐skin) to emulate the functionality human skin. Meanwhile, demand integrated power supply units is an additional pressing concern achieve its lightweightness flexibility. Herein, we propose self‐powered dual temperature–pressure (SPDM) sensor, which utilizes compressible ionic gel electrolyte driven by potential difference between MXene Al electrodes. SPDM sensor exhibits rapid timely response changes in pressure‐induced deformation, while exhibiting slow hysteretic temperature variations. These distinct characteristics enable differentiation current signals generated different stimuli through machine learning, resulting impressive accuracy rate 99.1%. Furthermore, developed wide range 0–800 kPa broad 5–75°C, encompassing environmental conditions encountered daily life. dual‐mode coupled strategy learning provides effective approach discrimination, showcasing applications wearable electronics, intelligent robots, human–machine interactions, so on.

In the realm of NH3 gas-sensing applications, electrically conductive nature Ti3C2Tx MXene, adorned with surface terminations such as −O and −OH groups, renders it a compelling material. However, inherent challenges atmospheric instability selectivity in presence gas mixtures have prompted exploration innovative solutions. This work introduces strategic solution through deposition mixed-matrix membrane (MMM) composed poly(vinylidene fluoride) (PVDF) matrix zeolitic imidazolate framework-67 (ZIF-67) filler. composite acts selective filter, permitting passage specific gas, namely NH3. Leveraging hydrophobic chemically inert PVDF, MMM enhances stability by impeding water molecules from interacting MXene. Furthermore, ZIF-67 is to via acid–base interactions within zeolite group pore size. The sensor embedded filter exhibits modest 1.3% change sensing response 25 ppm compared without filter. result underscores filter's effectiveness conferring diffusivity, particularly at 35% relative humidity (RH) °C. Crucially, attributes PVDF impart heightened even amidst varying RH conditions.
