Abstract
This paper presents a sustainable and environmentally friendly electronic skin (e-skin) made from a hydrogel composite using freeze-dried orange peels. The hydrogel matrix incorporates lyophilized orange mesocarp and a copper-based metal-organic framework (CuBDC) within a polyvinyl alcohol/hyaluronic acid matrix. This approach leverages intermolecular interactions for improved mechanical properties and self-healing ability. The resulting material demonstrates high elongation at break (290%), enhanced tensile stress, self-healing properties, conductivity (0.14 S/m), and antibacterial properties (95.3%). This research offers a promising avenue for creating eco-friendly e-skin materials.
