Newly Developed Smartwatch Uses Your Skin As A Touchscreen

Researchers at Carnegie Mellon have used electrodes to turn your skin into a touchpad extension for wearables like smartwatches.

The SkinTrack system uses four pairs of electrodes embedded in the watchband while a ring on your finger generates an electrical signal when you touch your arm.

This functionality makes things like drawing, and entering numbers look a dozen times easier than trying to get the corner of your fingertip to hit just the right way on a square-inch space on the actual device.

Of course hopefully, the next advance will be figuring out a way to ditch the sensor-tripping ring or at least get more stylish companies to partner with it.
