Wearables may get boost from boron-infused graphene

Rice U. researchers flex muscle of laser-written microsupercapacitors

(May 18, 2015) A microsupercapacitor designed by scientists at Rice University that may find its way into personal and even wearable electronics is getting an upgrade. The laser-induced graphene device benefits greatly when boron becomes part of the mix.

The Rice lab of chemist James Tour uses commercial lasers to create thin, flexible supercapacitors by burning patterns into common polymers. The laser burns away everything but the carbon to a depth of 20 microns on the top layer, which becomes a foam-like matrix of interconnected graphene flakes.
