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.
