Transparent Gesture Sensing film with Graphene-Pyroelectric Materials

Özyilmaz Group, Centre for Advanced 2D Materials & Graphene

Industry Problem

In the past decade, the method of interaction between humans and machines has gone from that based on primitive typing/mouse-based, to more advanced touch-based interfacing. Recently, smartphone manufacturers have launched technologies (such as Apple’s “3D Touch”) that extend this interaction into the third dimension, allowing users to “push” into their devices. However, technologies that truly unlock 3D through gesture sensing i.e. camera-based sensors, have all suffered from an inability to operate at close range while also draining battery life. Emerging technologies such as Augmented & Virtual Reality have also struggled to find suitable technologies to fill this niche.

Solution

Prof. Barbaros’ group from the Department of Physics has developed a transparent, stretchable film that acts as a motion (infrared) sensor, based on Graphene-Pyroelectric Materials. This film is a heat sensor, which is capable of tracking near-field human gestures, in turn allowing control over smartphones, computers & other display-based (wearables etc.) devices. The film’s transparency allows it to be “pasted” over any display based device, transforming the device into one that is compatible with gesture-based interactions. Due to the unique properties of graphene, the developed sensor is fast, sensitive and has higher responsivity compared to the conventional pyroelectric IR sensors. Furthermore, the film is more power-efficient than comparable cameras, as it generates its own power in response to human radiation. The flexible, transparent graphene-pyroelectric gesture sensing film is a first-of-its-kind technology, with no comparable solution developed in the past. The group is now working towards viable use cases for the technology, to highlight its full potential.
