Self-Welded Metal-Catalyzed Carbon Nanotube Piezoresistors with Very Large Longitudinal Piezoresistivity of ~ 4×10-8 Pa-1
Self-welded multi-walled carbon nanotube (MWCNT) bridges, grown using low-pressure metal-catalyzed chemical vapor deposition technique between silicon posts, were used as tiny piezoresistors to monitor vibration and bending/deformation of silicon cantilever beams for the first time. [...]
