In the present work,MoS2 decorated graphene nanocomposite powders were synthesized by laser scribing method.Theobtainedflexible light-scribed graphene/MoS2composites are very suitableas micro-supercapacitors and thus their performance was evaluated at different concentrations.The effect of laser scribing process to reducegraphene oxide (GO) was investigated. The GO/MoS2composite wassynthesized ...

Graphene application within electrochemical sensing has been widely reported, but mainly as a composite, which adds summative effects to an underlying electrode. In this work we report the use of laser-scribed graphene as a distinct electrode patterned on a non-conducting flexible substrate. The laser-scribed graphene electrode compared favourably to established carbon macroelectrodes when eval...

Supercapacitors, with the merits of both capacitors for safe and fast charge batteries high energy storage have drawn tremendous attention. Recently, laser scribed graphene has been increasingly studied supercapacitor applications due to its unique properties, such as flexible fabrication, large surface area electrical conductivity. With direct writing process, can be directly fabricated patter...

In virtue of its superior properties, the graphene-based device has enormous potential to be a supplement or an alternative to the conventional silicon-based device in varies applications. However, the functionality of the graphene devices is still limited due to the restriction of the high cost, the low efficiency and the low quality of the graphene growth and patterning techniques. We propose...

Since the first reported isolation of graphene by peeling graphite with cellophane tape in 2004, there has been a paradigm shift in research. In just nine years, graphene has had a major impact on fields ranging from physics and chemistry to materials science and engineering leading to a host of interdisciplinary advances in nanotechnology. Graphene is attractive because it possesses many extra...

Abstract Graphene has shown considerable potential for sensing magnetic fields based on the Hall Effect, due to its high carrier mobility, low sheet density, and low-temperature dependence. However, cost of graphene in comparison conventional materials meant that uptake electronic manufacturing been slow. To lower technological barriers bring more widespread adoption sensors, we are using a one...

Laser scribing is a technique that converts carbon-rich precursors into 3D-graphene nanomaterial via direct, single-step, and maskless laser writing in environmental conditions using scalable approach. It allows simple, fast, reagentless production of promising material with outstanding physicochemical features to create novel electrochemical sensors biosensors. This review addresses different ...

Pressure sensors are a key component in electronic skin (e-skin) sensing systems. Most reported resistive pressure sensors have a high sensitivity at low pressures (<5 kPa) to enable ultra-sensitive detection. However, the sensitivity drops significantly at high pressures (>5 kPa), which is inadequate for practical applications. For example, actions like a gentle touch and object manipulation h...
