Graphene-Based Flexible Sensors: Recent Advances and Challenges

Functional nanomaterials integrated, mechanically stretchable and biocompatible substrates have unique properties that find application in fabrication of flexible electronics on skin and textiles. These flexible wearable devices are used in wide range of applications ranging from flexible display/transistors, smart sensors, energy harvest and storage, smart artificial sensing skins for robots, aircrafts, human machine interaction and epidermal electronics for healthcare applications. This new type of flexible electronic devices can be further improved by amalgamating different conductive nanomaterials by various physico-chemical methods, such as additive ink and 3D printing, self-assembly, surface modification and transfer printing to overcome the conventional planar photo-lithography techniques. In this project, we will summarize recent advances in nanomaterials enabled synthesis strategies, materials and devices in combination with passive polymeric materials for electronic skin (E-skin) and electronic textiles (E-textile) applications.
