Effects of Electrode Design on the Melt Electrowriting of Sinusoidal Structures

Biranche Tandon

Melt electrowriting is a microscale manufacturing technique that uses polymer-based melts to create fibrous structures. An electric field is used to stabilize a continuous molten jet, which is then written onto a substrate as a microscale fiber. Herein, it ...
