Summary: A flexible textile-based DC generator utilizing the tribovoltaic effect has been developed, which can efficiently harvest mechanical energies to power self-powered wearable electronics. The generator is based on the dynamic Schottky junction between an Al slider and a poly(3,4-ethylenedioxythiophene)-coated textile, providing a voltage output of approximately 0.45-0.70 V. Connecting multiple generators in series can increase the voltage and current output, demonstrating the potential for continuous power supply to electronic devices without the need for conditioning circuits.

Summary: Transparent and flexible piezoelectric nanogenerators (ST-PENGs) based on PFOES and PVDF-HFP composite films were prepared, exhibiting a higher beta-phase content and remarkable piezoelectric properties. The hydrogen bonding interaction between the PVDF-HFP matrix and the PFOES agents causes a clear transition from phase to phase. These ST-PENGs generate an excellent output voltage, power, and sensitivity, exhibiting a record-high improvement compared with previously reported PENGs. This study may provide insight into the development of transparent and flexible piezoelectric devices for high-performance self-powered electronics.

Summary: Ionic conductive hydrogels have attracted significant attention in flexible/wearable electronics due to their flexibility, tunability, stimulus-response, and self-healing ability. However, traditional hydrogels face challenges such as loss of flexibility and conductivity when exposed to the environment. Organogels have emerged as a promising alternative that can overcome these drawbacks to some extent. This study introduces a self-polymerization reaction to create a super stretchable, anti-drying, and anti-freezing organogel ionic conductor (MOIC). The MOIC is used to construct high-performance triboelectric nanogenerators and multifunctional flexible/wearable sensors, demonstrating its potential for applications in electronic skin, flexible sensors, and human-machine interfaces.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
