Combining microelectromechanical system (MEMS) fabrication technology and electrophoretic deposition (EPD) can yield 2D and 3D carbon nanotube (CNT) patterns on either rigid substrates, such as silicon and metal, or elastic matrixes. The cover image is a resultant CNT pattern with a width of 50 μm imbedded on the surface of a polydimethylsiloxane (PDMS) matrix. Developed by Wenjun Xu and Mark G. Allen on page 1505, the technique is utilized to fabricate a stretchable CNT/PDMS strain sensor. Owing to the controllability of EPD, the correlation between the piezoresistivity of the system and the CNT network morphology on PDMS is established.
