New graphene-based recipes spur startups
At Mobile World Congress, a large stand regrouped different graphene-based prototypes from members of the Graphene Flagship consortium, all devoted to bring graphene into the mainstream, finding everyday life applications from re-enforced plastics to wearable sensors.

Another interesting demo was that of a capacitive-based pressure/force sensor demonstrated by Dr Yarjan Abdul Samad, research associate at the Cambridge Graphene Centre. By screen-printing graphene on both sides of a thin transparent plastic film, Samad and his team have developed cheap and flexible capacitive-based force sensors that could be used embedded in soles for running or gaming applications, but also for medical applications such as gait analysis. Here the demonstration consisted of a snowboarding video game where the player’s avatar (leaning forwards or sideways while surfing in snowy curves) could entirely be controlled through sensor-equipped shoes.

Heading up the startup Camsmart Technologies recently spun-off Cambridge University, improvised CEO Samad aims to commercialise the sensors. The startup is seeking partners to develop new solutions on a project basis, creating a library of designs and IP to address different market segments including industrial, medical and gaming.

 


Possible applications of the graphene-polymer
MEMS from Atomic Mechanics.

Founded in 2017, Manchester-based startup Atomic Mechanics was here to promote fully transparent flexible and stretchable graphene-polymer films turned into organic MEMS (Micro Electromechanical Systems) to create force-touch sensitive interfaces. Described as MEMS-TI, the MEMS consist of polymer-supported conductive graphene films freely suspended over a cavity. When a pressure is applied to the film, deformation of the graphene inward the cavity can be measured through the change of its electrical properties. But the same pressure/force sensor could be driven electrically as an actuator for haptic applications, claims the company on its website.


Atomic Mechanics’ MEMS-TI could differentiate
between taps and taps with maintained pressure.

The startup expects to be able to manufacture such MEMS devices in large quantities at a competitive price point. It wants to offer large-area transparent force/touch sensor arrays as interface overlays for screens of all sizes, possibly including haptic feedback all in one layer, with a high spatial resolution. Atomic Mechanics didn’t want to leak any specs yet but is working on a commercial release soon.
