Once again, a team of researchers from Korea has succeeded in developing multi-touch sensors based on graphene electrodes. A detailed article on the research called "Graphene-Based Three-Dimensional Capacitive Touch Sensor for Wearable Electronics" can be found in the July issue of ACS Nano.

The special feature of the Korean research is that the graphene electrodes for multi-touch and 3D sensors are able to function even on severely deformed surfaces. Which, in turn, provides a large number of additional uses. In a concrete example, this means that the transparent, thin, stretchable sensors are implemented on human body parts such as the forearm, palm or back of the hand, thus obtaining a multi-touch-capable surface that can be controlled with the finger (directly and indirectly).

The elongation of the graphene-based touch sensors is approx. 15%. In addition, non-contact contact is also possible (22 dB SNR at a distance of 7 cm). The complete research report can be purchased at the URL in our reference.
