Summary: Researchers successfully constructed an integrated photoanode by modifying BiVO4 with In2O3 layer and further decorating amorphous FeNi hydroxides, improving its performance significantly. The BV/In/FeNi photoanode showed a remarkable increase in photocurrent density and water oxidation reaction kinetics. This improvement was attributed to the formation of BV/In heterojunction inhibiting charge recombination and the decoration of FeNi facilitating the water oxidation reaction kinetics and hole transfer.

Summary: Highly sensitive soft pressure sensors have gained significant attention due to their potential applications in robotics, healthcare, and smart wearables. However, existing sensing mechanisms often result in large random errors, limiting their precision. In this study, a pure-polymer and field emission bilayer structure (PFEBS) is proposed to design an ultrasensitive and ultraprecise soft pressure sensor for the first time. The PFEBS enables uniform deformation of the sensing layer under subtle pressures, achieving a sensing precision with variation <1.62% and a sensitivity of 372.2 kPa(-1). This research offers a new design strategy for high-performance flexible pressure sensors.
