AI Technical Summary
Biodegradable films used in flexible electronics face challenges with poor mechanical properties, such as low tear resistance and brittleness, which compromise durability and reliability, and existing reinforcement methods often harm electrical, optical, or mechanical properties.
A biodegradable film structure with a substrate region and an integral local region, where the area of the integral local region is smaller than the film, formed of a second biodegradable material with a different elastic modulus than the substrate, immersed into the first biodegradable material, allowing for localized reinforcement without compromising overall properties.
This approach enhances mechanical strength and flexibility of biodegradable films while maintaining their electrical and optical properties, enabling customization of functional properties with minimal impact on the film's integral form, suitable for applications like ultra-thin conformal skin patches.
