Abstract

Pressure ulcers remain a significant healthcare concern, particularly among patients with limited mobility. This research presents the design and fabrication of a bio-inspired smart cushion pad made from natural rubber, integrating self-healing adhesive and self-recovery properties to enhance comfort, durability, and sustainability. The cushion was developed using a natural rubber latex compound molded and dried under controlled conditions to achieve stable mechanical performance. Results demonstrated excellent self-healing capability through ionic crosslinking interactions, along with strong adhesive bonding and consistent structural integrity after repeated damage–repair cycles. The incorporation of natural rubber offers an eco-friendly and cost-effective alternative to conventional synthetic or animal-based materials, while the self-healing and self-recovery mechanisms extend product lifespan and reduce waste. This innovation provides a sustainable, patient-centered solution for preventing pressure ulcers and shows strong potential for clinical and commercial applications.
