As a research fellow, my research uncovers MEMS switches, carbon nanotubes composites, contact mechanics and tribology. My expertise is on finite element modelling, especially on rough contact and multiphysics modelling.

Hong received her BSc and MSc degree in mechanical engineering from Shandong University, China (2006) and South China University of Technology, China (2009) respectively. She was awarded her PhD in mechanical engineering and material mechanics from Univsersité de Toulouse, France in 2013. The topic of her thesis was 'Finite Element Modelling of the Ohmic Contact for MEMS Microswitches'. With a strong passion for the research field, Hong joined the University of Southampton Malaysia Campus in 2013, and she is now the project leader of a Ministry of Education Malaysia grant ‘Contact mechanics of gold coated carbon nanotube microswitches.

Research project:

Contact mechanics of gold-coated carbon nanotube microswitches

(Ministry of Education Malaysia Grant)

Gold-coated Multi-Walled Carbon Nanotubes (MWCNT) surfaces have been shown to provide stable contact resistance for electrical contact switching applications under low force conditions (µN-mN). Due to the lateral gaps of the vertical aligned MWCNTs forest, the sputtered gold penetrated into CNT, making the Au/MWCNT a complex structure. Also, the surface presents a much higher roughness than metal surfaces.

The goal of the project is to investigate the mechanical and electrical behaviour of the Au/MWCNT surfaces, and to improve the performance and reliability of microswitches.
