With the growing demand for wearable technology, researchers are constantly on the lookout for innovative materials that can support flexible and interactive displays. However, a team from the University of California, Berkeley, has taken a different approach by focusing on something we use every day—plastic.
They've developed a 16x16-pixel electronic screen called "electronic skin," which lights up when touched. The harder you press, the brighter it glows. This technology could be used as interactive wallpaper, wrapped around your wrist, or even integrated into a car's dashboard for touch-based controls. The team believes this could one day give robots a more natural sense of touch.
The manufacturing process involves first solidifying a layer of plastic over a silicon wafer, then adding a layer of electronic components. After that, the silicon is carefully peeled away, leaving behind a flexible plastic film. Each pixel on the film contains a transistor, an LED, and a pressure sensor, making it highly responsive and adaptable.
While integrating sensors and networks is now common, this breakthrough lies in transforming data into something truly interactive. Unlike traditional touchscreens found on phones, computers, and ATMs, this electronic skin is not only flexible but also easy to attach to any surface, offering a new level of user experience.
Because the technology uses standard semiconductor manufacturing processes and relies on affordable plastic materials, it has great potential for real-world applications. Researchers are currently exploring how the electronic skin can detect changes in light and temperature, aiming to make it even smarter and more sensitive in the future. As development continues, this innovation could revolutionize how we interact with everyday objects and devices.
