Available to students on full-time physics degree schemes or joint students.
Graphene is a monolayer of carbon atoms, assembled in a honeycomb lattice that could ideally outperform even the highly conductive metals . A few lab-grown layers of graphene constitute a graphene paper. Due to good conductivity, thin flexible layer capable of bending and good surface uniformity, the graphene paper is a good choice for antenna fabrication on flexible substrates. Graphene papers are biodegradable, thus graphene-based antennas can avoid the use of costly metals and provide cheaper and environment-friendly solutions for wearable antennas. This project delivers a design/modelling, fabrication and testing of a graphene-based antenna for potential body-centric applications in smart wearables.
The project methodology has three distinct stages: 1) the literature review that involves the understanding of the potential of carbon-based advanced materials, 2) the suitable antenna design using graphene material with the help of a software and practical implementation and testing of the antenna performance, 3) Analysing the results, and deductions towards the future work.
In case if access to lab facilities is not possible, the project could be completed at home by using a standard PC/laptop provided that access to the computational design software is granted to the student. In that case, the fabrication part will be excluded from the project.
A successful project will develop beyond the above in one/some of the following directions:
This also implies on fabrication part in case if the testing facilities are delayed due to lab closing etc. However, having a comprehensive analysis based on simulation is also enough.
When considering where to take your project, please bear in mind the time available. It is preferable to do fewer things well than to try many and not get conclusive results on any of them. However, sometimes it is useful to have a couple of strands of investigation in parallel to work on in case delays occur.
Additional scope or challenge if taken as a Year-4 project: Several textiles based substrates will be used to implement the designed antenna to determine its suitability in electronic wearables. On-body lab testing of the fabricated prototypes of these antennas is needed and comparative analysis based on the performance will be made.
Please speak to Syeda Fizzah Jilani (sfj7) if you consider doing this project.
Initial literature for students:
The project’s scope emphasises the significance and use of biodegradable and environmental-friendly materials such as graphene in the construction of an antenna for potential applications in wearable electronics. The project will enable the student to gain a theoretical understanding of electromagnetic principles associated with an antenna design for radio frequency (RF) spectrum as well as expertise of a computational software. At the end of the project, the student will have a knowledge of utilisation of carbon-based advanced materials for RF communication in smart wearables designed for practical applications like clinical diagnostics.
