Maskless patterning of electrodes for 3D deformable and stretchable electronics applications

Recently in-mold or 3D deformable electronics and stretchable electronics areas have gained a lot of attention from academia and industry for sensor, bio, energy and display applications. Most of high-end, close-to-commercialization technologies are based on using conventional mask-based patterning methods on a flexible but not stretchable plastic substrate and reforming the final flexible device so that it can be stretched or 3D deformed. However, in order to make final working device directly on either a stretchable or 3D deformable substrates, a new maskless patterning method must be used. The direct maskless patterning will have a significant benefit if it is easy to use and it can be universally applied to various conductive materials.

In this talk, I will show you our group's efforts developing maskless pattering methods for solution-process AgNW and other various vacuum deposited electrodes for potential usage in stretchable or 3D deformable electronics application.
