A biologist has created a soft silicone digital clock that does without electricity. Instead of circuits, it uses internal microchannels through which colored liquids circulate, driven by compressed air. This design suggests that everyday devices of the future could be flexible, safe, and free of batteries or rigid components, opening up new possibilities for screens and portable gadgets.
Microchannels and air: fluid mechanics as a replacement 💧
The mechanism is based on a network of tiny channels within the silicone. When air pressure is applied, the tinted liquids move in a controlled manner, forming the digits on the clock display. This pneumatic system eliminates the need for metals, soldering, or batteries. The device is completely soft and can be bent without breaking, representing an advance in materials for flexible electronics and applications where rigidity is a problem.
Goodbye to chargers: now you'll have to inflate the clock 🎈
If you thought charging your phone daily was a pain, get ready for what's coming. The future of technology could include a small air compressor in your backpack to wind up the clock. Forget looking for an outlet; now what you need is a can of compressed air. And if it deflates mid-afternoon, you can always blow hard as if you were inflating a birthday balloon. The soft revolution has arrived, but it brings its own logistics.
