Nanotube-based technology for microelectrical-mechanical systems.(NANOMATERIALS)

According to scientists in Taiwan, microcantilever actuators made from carbon nanotube (CNT)-polymer composites could improve the performance of microelectro-mechanical systems. The researchers--from National Tsing Hua University--have developed an easy to actuate material that rapidly suppresses unwanted oscillations.

To make the material, the researchers first grew multi-walled CNTs on an iron-defined polysilicon substrate, and then exposed the substrate to polymer vapour. The CNT--polymer actuators are formed by removing the underlying polysilicon with vapour-phase xenon difluoride. Images show that the aligned nanotubes are curled into spring-like structures that act ...
