Sew and Transfer Method for Fabricating Highly Stretchable, Robust Electrical Interconnects
- Summary
- Purdue University researchers have developed a novel, sew and transfer method for rapid fabrication of low-cost, highly stretchable interconnects. Using a commercial sewing machine and double-thread stitch, with one of the threads being water-soluble polyvinyl alcohol (PVA), thin zigzag pattern metallic wires are sewn into a polymeric film and are subsequently transferred onto a stretchable elastomeric substrate by dissolving PVA in warm water. The resulting structures exhibit extreme stretchability and robustness.

- *Abstract
-
- *Background
- Fabricating highly stretchable, robust electrical interconnects at low-cost remains an unmet challenge in stretchable electronics. Previously reported, stretchable interconnects require complicated fabrication processes with resulting devices exhibiting limited stretchability, poor reliability, and large gauge factors.
