摘要：

Miniaturisation has proven its powerful driving force towards the development and modernization of our society in the last few decades. There is still an increasing interest in the incorporation of active materials into conventional microelectromechanical systems (MEMS) components and devices, in order to expand the functionality and improve the performance.  The ability to fabricate functional materials and components with feature sizes <1mm is a key enabling step, and will help the drive for miniaturization and integration of materials and system, the increase of multi-functionality, and cost effective manufacture. This talk will focus on colloidal powder-based routes for the fabrication of micro-/macro-sized ceramic components and devices. Using colloidal routes, there is a high degree of processing flexibility depending on the ceramic volume fraction and rheology of the powder – binder - fluid system. Candidate processes include printable thick film ink systems, castable ceramic slurries, and viscous, plastically deformable tapes. A range of patterning and/or shaping routes including screen printing, moulding and plastic-forming can be used with these different colloidal systems to produce components with feature sizes in the range 10-100 m.
