Researchers present electronic tattoos as new controls

employees Google together with computer scientists of at Saarland University a new operating concept for simple functions of mobile devices showed. The “SkinMarks”, which they have developed similar tattoos from gum packaging applied on the skin and provide touch over short distances as commands to the device, which essentially meant for a few basic commands. The developers according to the decisive advantage is that the control over the SkinMarks can be completely intuitive and without eye contact, because their position on the body is always aware people.

the specialists tested also new forms of input. An “e”tattoo can be glued, for example, on the inner side of the index finger. Is deleted with outstretched fingers with one another about it, a music player’s volume could be regulated thereby. Curved finger pressing on one of the three links to the current song or a song to stop, is above or to jump back.

skin marks shown currently are a further development of the 2015 presented , iSkin mentioned, elastic sensors. An advantage of iSkins developed together with colleagues of at Carnegie Mellon University to Smartwatches researchers called the greater flexibility at that time: while the operable interface of a Smartwatch is rigid and small, which makes it difficult to hit individual keys, an iSkin could be much larger without uncomfortable to stand out.

the touch-sensitive stickers are meant to be stuck on the forearm and connected to the Smartphone. Such a call can be accept or adjust the volume by pressing. However, the comparatively large iSkins assume even a relatively flat surface.

with the skin marks the concept was now by the doctoral students Martin Weigel and Aditya Shekhar Nittala, as well as their Professor Jürgen Steimle and the Google employee Alex Olwal refined. Task was to find the right combination of conductive ink and printing process allow conductors and electrodes sufficiently compact and thin on the tattoo paper print. She could with the conductive polymer PEDOT: PSS are met.

so the tattoo can print the researchers of thinner than a hair. It should be ensured that’s about sets of knuckles and wrinkles, is but also flexible enough to withstand the inevitable movements compression and extension.

the SkinMarks also transmitted with water on the skin, is”after a few days’ detach again. Currently, scientists can make a such electric tattoo within 30 to 60 minutes in the laboratory. Should the product reach market maturity, that is their opinion but faster. And could an “e”tattoo can be make in less than a minute by anyone on a commercially available printer in the future, predicts Professor Steimle.

Google works with scientists from the Saarland in other areas. 2015 of the US-based Group participated in the local German Research Center for artificial intelligence (DFKI).

Wieland get fields, engineering Director at Google Germany, explained at the time the Group see much potential for artificial intelligence in particular for self-driving cars, would be where a large amount of sensor data that must be processed. In General, DFKI as cooperation partner for Google is interesting but above all technologies for the analysis of images, videos and spoken and written language.

Google translate has already worked with algorithms that have been developed in a DFKI project. Another focus of the collaboration between Google and the DFKI is an analysis of image software, developed by the research company. With which you can automatically detect illegal content. Google could use the software to cover up illegal content in its databases or even upload to prevent.
