Abstract: Fabric-based pressure sensors offer high stability, low energy consumption, and excellent wearing comfort, making them promise intelligent wearable devices and health monitoring. However, creating a fabric-based capacitive pressure sensor that integrates high sensitivity, wide detection range, good air breathability, water vapour permeability, and low cost remains a challenge. In this study, a sensor two-scale synergistic resistive/capacitive hybrid response model is developed to analyze the sensor response factors at different pressing stages. It is proposed that fabric metal silver electrodes be prepared using the microdroplet jetting technology, combined with the sacrificial template method and mixed doping of active materials to prepare the dielectric layer. Results indicate the sensor achieves a high sensitivity of 2.872 kPa^-1 within a pressure range of 0-1 kPa, with an average air breathability of 61.69 mm/s and water vapour permeability of 3075.01 g/m² 24 h. Its applications in human motion monitoring and human-computer interaction highlight its potential in wearable technology.
