Abstract Bimodal pressure sensors capable of simultaneously detecting static and dynamic forces are essential to medical detection bio-robotics. However, conventional typically integrate multiple operating mechanisms achieve bimodal detection, leading complex device architectures challenges in signal decoupling. In this work, we address these limitations by leveraging the unique piezotronic effect Y-ion-doped ZnO develop a sensor (BPS) with simplified structure enhanced sensitivity. Through combination finite element simulations experimental validation, demonstrate that BPS can effectively monitor both forces, achieving an on/off ratio 1029, gauge factor 23,439 force response duration up 600 s, significantly outperforming performance piezoelectric sensors. As proof-of-concept, demonstrates continuous monitoring Achilles tendon behavior under mixed loading conditions. Aided deep learning algorithms, system achieves 96% accuracy identifying movement patterns, thus enabling warnings for dangerous movements. This work provides viable strategy monitoring, highlighting its potential wearable electronics.

Photothermal therapy (PTT) is a cutting-edge technique that harnesses light energy and converts it into heat for precise tumor ablation. By employing photothermal agents to selectively generate target cancer cells, PTT has emerged as promising treatment strategy. Notably, therapies conducted in the second near-infrared (NIR-II) window exhibit superior therapeutic outcomes, owing deeper tissue penetration reduced scattering. In this study, we developed biomimetic NIR-II aggregation-induced emission (AIE) nanoparticles (2TB-NPs@TM) high-efficiency imaging targeted phototherapy of ovarian cancer. The core nanoparticle aggregates (2TB-NPs) display strong fluorescence high conversion efficiency, while outer cell membrane coating facilitates active targeting recognition tissues. This design imparts excellent biocompatibility enhances drug delivery leading potent synergistic effects. Our findings open new avenues advancing targeted, high-performance diagnostics treatment.
