Abstract
Disclosed are examples for printing a one-dimensional (1D) nanomaterial for use in stretchable electronic devices. An ink comprising a nanomaterial solution is dispersed from a pneumatic dispensing system of a printing device. The 1D nanomaterial is printed in a predefined pattern on an underlying substrate positioned on a ground electrode. A voltage is applied between the printing nozzle and the ground electrode to cause the ink to form into a cone during the printing. The substrate can be modified to increase the wettability of the substrate to enhance adhesion of the ink to the substrate.
