From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

A Comparison Study on Mechanical Properties of PVC Composites Filled By Graphene Oxide (GO) and Reduced Graphene Oxide (RGO)

Pamukkale University Journal of Engineering Sciences, 2019
Graphene derivatives (graphene oxide-GO, reduced graphene oxide-RGO, multi-layer grapheme-MLG, etc.) generally are considered to be extremely significant fillers to improve properties of polymer materials. In this work, the mechanical properties of the composites according to filler type and filler loading were investigated.

Vortex beam generation from reduced graphene oxide(rGO)-polymer

Optical Materials Express, 2019
We have obtained reduced graphene oxide (rGO) by reducing the graphene oxide (GO) polymer using a femtosecond (fs) pulse laser. A method for the fabrication and preparation of GO-polymer composite is first described. We then discuss the reduction of GO-polymer to rGO using direct laser writing technology.
