In this report, the prototype of micro-supercapacitor (MSC) arrays based on the art of paper folding (Miura folding) were demonstrated as foldable and miniaturized energy storage components. The Miura folding is a method to fold a flat surface into crease patterns consisting of parallelograms with smaller areas. Here each MSC unit was made by deposition of conductive graphene sheets followed by plasma...
The rapid development of miniaturized electronic devices requires state-of-the-art small-form-factor energy storage units for power supply. Micro-supercapacitors (MSCs), as microscale supercapacitors, have great potential to replace microbatteries or electrolytic capacitors due to their high power density and long cycling stability. The planar design of interdigital microelectrodes not only shortens...
We present a novel approach to fabricate the biocompatible and stretchable micro-supercapacitors (MSCs) as energy storage units in electronic devices. The interdigital micro-patterns were embedded into polydimethylsiloxane (PDMS) substrate via a combination of microelectronic fabrication techniques. Graphene, as a biocompatible form of carbon, was used as the electrode material due to its high electrical...
We report a strong electron-photon interaction in exfoliated graphene observed at room temperature. Graphene has great potential to optoelectronic applications because of its excellent optical properties. Here, we demonstrate using the graphene-based structure for infrared detection under a zero-bias operation. When infrared light is projected to graphene, the graphene is capable to generate photocurrents...
