Recently,flexible electronic devices have gained
tremendous research interest owing to their wide range of
applicationssuch as humanmotion detection, healthmonitoring
and electronic skin (E-Skin). Particularly, the development
of skin-like flexible strain sensors is gradually increasing for
the realization of multipurpose human-machine interfaces.
This paper aims to propose a simplemethod ofmanufacturing
flexible graphene-based strain sensors with high sensitivity.
Herein, a novel flexible resistive-strain sensor based on
graphene nanoplatelets (GNP)/PDMS has been reported that
providesgood strain sensitivity,stretchabilityup to 65%with a
gauge factor of 62.5, indicating typical piezo-resistive characteristics.
The fabricated sensor is attached to the human body,
it works as a health-monitoring device by detecting various human motions such as human wrist pulse measurement,
the finger bendingmovement and in addition to the flexible pipe bending. This work presents fabrication, characterization
and comparative study of four different types of GNP wrist pulse sensors. Therefore, with its simple structure and low
cost processing coupledwith reasonably good piezo-resistive behavior, it has great potential in wearable electronics, viz.
human motion detection and health monitoring applications. |
