摘要

Conductive composites based on nanocellulose, polyvinyl alcohol, and iron, oriented by a magnetic field (Fe-NC-PVA), were fabricated. The study examined the surface morphology, chemical composition, mechanical, and electrical properties of the composites depending on the iron content. It was found that in terms of mechanical strength and electrical resistance, the recommended iron content in the composite varies from 0.13 to 0.25 g. Biodegradable planar bending sensors were made from this material that are characterized by the following parameters: gauge factor – 2–3, reversibility – 98–99%, time drift – 0.01–0.02%/min, complete biodegradation time of sensitive element in soil – 5 months. The obtained sensors were successfully used to study human motor activity (movements of the upper and lower limbs, finger touch, squatting, walking, etc.).
