Moisture detection plays a crucial role in physiological monitoring and wearable electronics. Nevertheless, most of the humidity sensors were restricted by power supply, hindering their applicability internet things mobile healthcare. Herein, we reported hierarchical piezoelectric composite film for active biomonitoring. The as-electrospun transducing textile consists samarium-modified lead magnesium niobate titanate piezoceramic fillers polyvinylidene fluoride matrix, while spin coated polyimide serves as sensitive layer. By tuning thickness ratio between layer sensing well porosity electrode, an optimal moisture-sensing performance was accomplished with high response ∼500% rapid response/recovery time 23 s/31 s. Furthermore, theoretical modeling mechanism established combining thermodynamic derivation finite element calculation.

Smart sensors capable of detecting NH3 at sub-ppb levels are important for human health in our daily life. Here, we demonstrate a surface acoustic wave (SAW) sensor based on ZnO@MXene hybrid heterostructure ultrahigh gas detection under UV illumination room temperature (RT). Under illumination, the SAW not only significantly enhances frequency response (Δf ≈ 32.24 kHz/20 ppm) but also effectively improves selectivity with low limit (89.41 ppb), short response/recovery times (92/104 s), long-term stability, and robust sensitivity various relative humidity conditions (dark) to RT. These unique sensing properties might be attributed enriched functional groups, oxygen vacancies, excellent charge transfer Schottky barrier via band bending, which is explained using an energy theory mechanism. Overall, current study offers strategic insights designing light-activated high-performance SAW-based RT safety assurance environmental monitoring.

Integration of multiple superior features into a single flexible pressure sensor would result in devices with greater versatility and utility. To apply the device to variety scenarios solve problem accumulation e-waste environment, it is highly desirable combine degradability wide-range linearity characteristics device. Herein, we reported degradable multilayer fabric (DMF) consisting an ellipsoidal carbon nanotube (ECNT) polyvinylpyrrolidone/cellulose acetate electrospun fibers (PEF). The alternative layer-by-layer stacking ECNT PEF notably accelerates sensitivity toward pressure. optimized demonstrated 3.38 kPa-1 over wide measurement range from 0.1 500 kPa, as well great mechanical stability 2000 cycles. A good degradation performance was confirmed by both Fourier transform infrared (FTIR) characterization decomposition experiments sodium hydroxide solution. fabricated capable precepting physiological including subtle arterial pulse, dancing training, walking postures, accidental falls. This work throws light onto fundamental understanding interfacial coupling piezoresistive materials provides possibilities for design development on-demand wearable electronics.

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. Theoretical modeling established combining Kelvin probe force microscopy characterization electron cloud overlap energy band derivation. This work not only offers unprecedented insight into fundamental mechanism but also opens up possibility development next-generation wearable electronics.
