... that turn your body into a touchpad and holographic glasses that can be paired with a phone

• Google has been experimenting with a range of new wearables
• Technology includes rub-on smart tattoos that act as touchpads
• They can be applied to one's skin and read swiping and pinching gestures
• Google has also been working on holographic glasses
• The hardware is similar to Google Glass which was discontinued in 2015

Experimental divisions at Google have been working on the next generation of wearables.

As noted by CNET, the tech giant has quietly been funding or conducting its own research into a host of new wearables devices including an entirely novel 'smart tattoo' that turns one's skin into a temporary touchpad. 

The technology, called SkinMarks, is being developed by Google and researchers at Saarland University in Germany and uses a small patch loaded with sensors.

SkinMarks use conductive ink which is printed onto tattoo paper and then applied to the side of one's finger or knuckles.
