Aligned multiwalled carbon nanotube (MWNT)-polymer composites are synthesized for use in microelectromechanical systems (MEMS) applications. Indentation and bending tests reveal that the elastic modulus of the MWNT-MEMS devices is promoted by a factor of 20. Dynamic bending experiments show that MWNT-MEMS devices can be driven at a lower pull-in voltage compared with classical devices. Complex and delicate MWNT-MEMS devices can also be fabricated (see Figure).
