Flexible and sensitive pressure sensor with enhanced breathability for advanced wearable health monitoring

Year: 2025

Type: article

Abstract: 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.
