Project Title          Design and characterization of Laser Induced Graphene (LIG) flexible gas sensors for wearable electronics application

Start Date             Sept 01, 2020

End Date               March 31, 2024


Contact Person: Dr. Ling Ting Yang/


Nationality Requirements on Candidate(s): Applicants should be Malaysian citizens


Minimum requirements: Outstanding mathematical background and a first class honours degree (or equivalent) from top-tier universities. Strong English writing, and experience in hardware design, micro/nano characterization is an advantage.

Details: Upon successful completion of the study, PhD degree will be awarded by the University of Southampton, UK. The candidate will be supervised by ASSISTANT PROF. DR. Ling Ting Yang, and an academic from the UK campus during his or her study. The candidate may have the opportunity to spend part of the PhD in the UK campus.


Recent advances in material technology has demonstrated great potential for new applications in flexible electronics. A wide range of application such as flexible displays, mechanical sensors (strain, pressure, motion etc.), and bio-electrical sensors (galvanic skin response, EEG, ECG, etc.). Most of these sensors consists of an active sensing layer and a flexible substrate. Typically, the active sensing layer are made from either conductive polymer, metallic nanoparticles, or carbon-based materials. Laser Induced Graphene (LIG) is being investigated intensively since its discovery in 2014 as it provides a low-cost and accessible route to fabricating graphene on flexible substrates without requiring substrate transfer. LIG is fabricated by laser scribing of polyimide, a commercially available polymer film. The properties of LIG, such as its porosity, surface structure, thickness and conductivity, can be manipulated by controlling the lasing parameters of the CO2 laser used. For this project, the selected candidate will be expected to study the effect of different surface functionalization on the sensing effect of LIG. The candidate will also be carrying out in-depth characterization on the properties of LIG and functional materials in order to design a useable gas sensor on a flexible substrate.

Benefits: In addition to tuition fees exemption, a monthly stipend of RM2,300 will be available during Malaysian residence period (up to three and half years). Similarly, a monthly stipend during UK residence period (three to six months) will also be available if travel is required (a reasonable allowance will be given.).
