Parts of the screen may swell and deflate with liquid. it's hard to touch. Researchers Craig Schultz and Chris Harrison from the Future Interfaces Group (FIG) at Carnegie Mellon University have created a miniature shape-shifting display using embedded electroosmotic pumps. The developers announced this on their website.
According to experts, embedded electroosmotic pumps are arrays of liquid pumps on a thin layer embedded in a sensor device such as a smartphone or car display.
When a display element needs a button, the liquid fills the space of the layer and the top panel bends to take that shape.
They are fed directly from the applied voltage, have a thickness of 1,5 mm and allow complete stacks of less than 5 mm to be formed. However, they can move the entire volume of liquid in one second.
When the software releases it, it returns to the viewing plane.
