In a bid to push foldable technology beyond its current limitations, Samsung has patented two innovations that could redefine how flexible smartphones handle wear and tear. The first patent outlines a self-healing camera lens coating that can automatically repair minor scratches and abrasions over time. This feature would be especially useful for foldables, where exposed lenses are more vulnerable to damage due to frequent opening and closing.
The second patent focuses on a self-healing fingerprint sensor, embedded beneath the foldable display. This sensor is designed to recover from pressure-induced deformations, ensuring consistent biometric performance even after repeated use. The healing process is triggered by heat or light exposure, allowing the material to gradually return to its original state without manual intervention.
Both technologies rely on polymer-based materials that exhibit elastic memory and surface regeneration properties. While self-healing coatings have been explored in other industries, their application in consumer electronics—especially foldables—is still emerging. Samsung’s patents suggest a future where foldable phones not only bend but also bounce back from physical stress.
These developments align with Samsung’s broader strategy to lead in foldable innovation. The company has already introduced ultra-thin glass and hinge durability improvements in its Galaxy Z series. Adding self-repairing components could further enhance longevity, reduce maintenance costs, and improve user trust in foldable reliability.
It’s unclear when or if these technologies will appear in commercial products, but the patents indicate Samsung’s intent to solve one of the biggest pain points in foldable design: fragility. If successful, self-healing features could become a standard in next-gen foldables, setting Samsung apart in a competitive market.
