However, a perfect graphene is robust and has a low piezoresistive sensitivity. So scientists have been driven to increase the sensitivity using different kinds of methods since the first graphene-based strain sensor was reported. We give a comprehensive review of graphene-based strain sensors with ...

constant was in the range 1–5 N/m and the Young's modulus was 0.5 TPa, which differs from that of the bulk graphite. These high values make graphene very strong and rigid. These intrinsic properties could lead to using graphene for NEMS applications such as pressure sensors and resonators...

Sweat is a biofluid with rich information that can reflect an individual’s state of health or activity. But the real-time in situ sweat sensors lack the ability of long-term monitoring. Against this background, this article provides a holistic review on the necessary process and methods for ...
Liu et al. created a non-invasive technique for ongoing IOP monitoring by utilizing a novel strain gauge material composed of graphene nanowalls. They investigated the relationship between the corneal strain, CLs, and IOP through experimentation. To enable the non-invasive IOP monitoring, a new ap...
After the successful preparation of graphene,[15] it has immediately been attracted the attention of researchers due to its excellent properties such as high carrier mobility, abundant adsorption sites and high specific surface area.[16,17] The successful applications of graphene as gas sensors[18–...
The developed graphene-based pressure Conclusion This paper provides a review of biomimetic tactile sensors and signal processing with spike trains. Parallel to the review of the human sense of touch with an emphasis on the properties of human mechanoreceptors and human tactile stimulus perception, ...
