There’s an article over on the BBC web site that talks about a division of Samsung that has started to license a quantum physics “trick” known as Quantum Tunneling Composite. For example, the technology could be used to allow you to scroll a web page faster the more pressure you apply to the touch screen.
Quantum physics is one of those classes that I never really got along with at university. So I won’t pretend to understand exactly what’s happening here. The end result is a pressure sensitive switch that’s about the same thickness as a human hair, and only requires power when it’s pressed.
The article makes no mention about what devices and manufacturers are planning on using this technology or how it will effect the price of the unit. Regardless, I think it’s awesome use of technology and I can’t wait to give it a run myself.
