Effect of Lubricant Viscosity on the Friction Behavior of the mm-scale Specimen
Wu, Jian; Sørby, Knut (Chapter, 2021)The size of moving parts in MEMS (micro-electro-mechanical-systems) is often in the mm-scale or smaller. Affected by the size effect, the friction in the mm-scale is different from the friction larger systems. In this ... -
A measuring method for micro force based on MEMS planar torsional spring
Wu, Jian; Liu, Tonggang; Wang, Kesheng; Sørby, Knut (Peer reviewed; Journal article, 2020)In order to measure the micro force in a micro-nano device, a new measuring method for micro force is introduced. In this paper, a measuring system based on a micro-electro-mechanical systems (MEMS) planar torsional spring ... -
A Pin-on-Disk Tribometer for Friction and Lubricating Performance in mm-Scale
Wu, Jian; Liu, Tonggang; Yu, Ning; Cao, Jiejie; Wang, Kesheng; Sørby, Knut (Peer reviewed; Journal article, 2021)A pin-on-disk tribometer for micro-scale applications is presented in this paper. The tribometer consists of a stationary mm-scale pin and a rotating disk. Friction and lubrication film thickness are measured by a laser ...
