Carbon Nanotube Composite Surfaces for Electrical Contacts of MEMS Switches Seminar

17:00 - 18:00
13 April 2015

Event details

MEMS switches have been forecast as a multi-billion (US$) technology area for over 20 years. As yet this has not been achieved, largely due to the inability to resolve the tension between achieving a high conductivity while achieving the necessary very high switching lifetimes. John McBride and his group at the University of Southampton (UoS) have used gold coated multi-walled carbon nanotubes (Au/MWCNT) composite as one contact surface, which combines the advantages of low electrical resistivity of gold top layer and compliance of MWCNTs ‘forest’ under layer, and the experiments showed that this novel composition can significantly improve the device lifetime. In the seminar, I will introduce the Au/MWCNT composite, the usage of the composite as the material for electrical contact in MEMS switches, and how it improve the lifetime of the electrical contact.
