Touchscreens that Look Like Temporary Tattoos

Full Story –

Unlike the rigid wearable touch-pad technologies currently on the market, like the hard-surfaced Apple Watch, iSkin can pick up touch input even when the film is being stretched or bent, making it ideal for the wear and tear of daily life.

The iSkin’s electrode design features resistive touch sensing, with a ‘sandwich’ of two electrodes, top and bottom, that are held apart by perforated layers of silicon. The design even has a built-in form of pressure sensitivity, though it only has two layers. Bringing your finger close to the electrode, the first degree of pressure, reduces the capacitance slightly. But actually pressing on the electrode creates a contact between both electrodes, closing the circuit. The sensor is also capable of capturing multi-touch input.
