Graphene-based Microsupercapacitors and Sensors for Wearable Electronics
Graphene, a 2D hybridized carbon layer with a hexagonal honeycomb lattice, has attracted great research attention. Graphene has several derivatives, such as graphene oxide, reduced graphene oxide, which can be mass-produced using simple solution process. With unique physical and chemical properties, graphene-based materials have been extensively used for high performance energy storage devices, sensors etc.
In this talk, I will briefly introduce some of my recent work on fabrication microsupercapacitors (MSCs), pressure sensors and electronic skins for wearable electronics using graphene-based materials. First, in-plane MSCs were fabricated using conventional photolithograph process, exhibiting attractive electrochemical performance. Fiber MSCs were also fabricated using rGO as the electrodes. Graphene-based materials are also excellent candidates for high performance sensors, including pressure sensors and E-skins, which will also be introduced in the talk. Finally, I will give some brief perspectives on future directions of graphene-based devices for wearable electronics.
