Tactus is producing magic-like hardware with “real physical buttons that dynamically appear and disappear into a flat touch screen,” according to their website. A thin layer, composed of semi-elastic polymer, is placed atop a smartphone or tablet. Microfluidics enable the buttons to appear so you can type and/or play games on the device.
Researchers at the Swiss Federal Institute of Technology in Zurich (ETH Zurich) have created clear, flexible electronic circuitry that is so thin it can sit upon the surface of a contact lens, or be wrapped around a human hair. The research, led by Dr. Giovanni Salvatore, could ultimately be used for implantable medical devices. One such potential application suggested by the team is a “smart contact lens” that could monitor intraocular pressure for glaucoma patients.
