Abstract:
With the increasing demand for wearable sensing devices equipped with hydrogels for motion intent recognition and health monitoring applications, it is urgent to carry out research on enhancing their comfort and breathability. Gel/PVA/DPy breathable hydrogels with high breathability, excellent electrical conductivity, and sensing ability were prepared by the fermentation method using gelatin and polyvinyl alcohol to create a dual-network structure of hydrogels with Dopamine-modified polypyrrole(DPy) serving as a conductive filler. The prepared hydrogel film exhibits excellent air permeability (5.83 mg·cm−2·h−1), tensile sensitivity (GF=5.14), compressive sensitivity (GF = 5.33), outstanding responsiveness to external tensile stimulation (response time of 0.30 s, recovery time of 0.20 s), and exceptional responsiveness to external compressive stimuli (response time of 0.20 s, recovery time of 0.30 s). The film is utilized as a high-sensitivity, high-precision wearable sensor for monitoring activities such as finger bending, facial micro-expressions, wrist swinging, and throat vocalizations; for real-time pressure-sensitive arrays; and for controlling electronic devices for gaming. This study offers a design concept and reference for preparing breathable hydrogel films for wearable sensors. © 2025 Elsevier B.V.
