With the rapid advancement of smartphone technology, glass has become a key material in the design and manufacturing of modern devices. Unlike plastic, which once gave off a cheap and less durable impression, glass offers a more premium feel and a refined aesthetic. However, this shift has also introduced new challenges—glass is more fragile than plastic, making smartphones more susceptible to damage from drops, which has led to the rise of screen protection services and phone insurance products.
On December 21st, researchers at the University of Tokyo announced a groundbreaking development: they have created a self-healing glass that can repair cracks on its own when pressed. After a short period, the material regains its original structure, offering a promising solution to one of the most common issues with smartphones.
This innovative material is based on a unique polymer called "polyether thiourea." The discovery was made unexpectedly by a student researcher named Yu Yanagisawa, who initially intended to use it as an adhesive during an experiment. To his surprise, the material not only bonded surfaces but also had the ability to heal itself within a few hours.
If this self-healing glass is successfully integrated into smartphone production, it could revolutionize the industry. Users would no longer need to worry about dropping their phones or breaking the screen, significantly reducing repair costs and increasing device longevity. This breakthrough may also inspire further research into other self-repairing materials for use in various industries beyond consumer electronics.
