Imagine a screen that doesn’t just show images but also changes its shape when you touch it.
Engineers at Rice University and Kyung Hee University have developed a new soft, shape-shifting surface that can move, sense its own shape, and even light up to communicate with users in real time.
The breakthrough could lead to more natural ways for people to interact with computers, robots, wearable devices, and virtual reality systems.
The research, published in Science Advances, introduces a flexible mechanical surface that can safely be pressed, pinched, twisted, and squeezed without being damaged.
Unlike traditional touchscreens that mainly rely on visual displays, this new technology combines both touch and sight, creating a much richer interactive experience.
The researchers believe future electronic devices should communicate with people in ways that feel more like interacting with everyday objects.
To explain the idea, one of the researchers compared it to choosing an avocado at the supermarket. People do not simply look at an avocado to see if it is ripe. They gently squeeze it because touch provides important information.
The new surface is designed to work in a similar way by responding physically when people interact with it.
The device is made up of a grid containing 36 soft, flexible sections called pixels. Hidden underneath are electromagnets that carefully raise or lower each section using magnetic forces. Because every pixel can move independently, the surface can create more than a trillion trillion trillion different shapes.
During demonstrations, the researchers showed the surface creating moving waves, ripple patterns, checkerboard designs, and even movements similar to the beating of a human heart. In another experiment, the changing surface directed tiny drops of water into different letter shapes.
One of the most impressive features is that the surface can sense its own movements without using external cameras.
Tiny motion sensors are built directly into the flexible material. These sensors continuously monitor how each part of the surface tilts and moves, allowing the system to calculate its overall shape almost instantly.
The engineers also added a grid of colorful LED lights that change color as the surface moves. This allows the device to provide visual feedback that matches its physical movement. In one demonstration, a small paper boat floated on the moving surface while blue lighting effects created the illusion of rolling ocean waves.
The researchers designed the system to work much like the human body. The soft upper layer acts like skin, a firmer lower layer provides support like bones, magnets function like muscles that create movement, and sensors act like nerves that detect motion and send information back to the system.
One major challenge was controlling the powerful magnetic forces accurately. The team developed a mathematical model that predicts exactly how much electrical power is needed to create each shape, allowing the surface to change form much more quickly.
The researchers believe this technology could eventually be used in education, soft robotics, wearable electronics, virtual and augmented reality, and assistive devices for people with vision loss.
By combining touch, movement, and visual feedback, the new shape-shifting surface could make future human-machine interactions feel far more natural than today’s flat screens.
