Flexible and sensitive pressure sensor with enhanced breathability for advanced wearable health monitoring
Flexible wearable sensors are crucial for health monitoring and motion detection, but they are often hindered by inadequate breathability and comfort. Here, we present a breathable pressure sensor that combines MXene nanosheets with a porous polyester textile, achieving high sensitivity (652.1 kPa⁻¹), a broad detection range (0–60 kPa), and a fast response/recovery time (36 ms/20 ms). The serpentine electrode pattern enhances tensile strength and sensitivity, while electrospun TPU nanofiber membranes improve breathability and signal recovery. A 4 × 4 electrode array allows for precise pulse localization, while machine learning algorithms enable real-time blood pressure prediction. This innovative design demonstrates significant potential for wearable health monitoring and cardiovascular diagnostics.
