The Cost

Interconnects that can deform under monotonous and/or repeated loading are increasingly important to a new class of electronic devices used for wearable applications. Such interconnects integrate different material sets such as polymers and metallic conductors and are subjected to large strain levels. A typical method to overcome the material incompatibility involves the conductor in the form of a serpentine or an out-of-the plane buckled geometry. In this paper, we demonstrate a novel combination of interconnect materials that enables significant improvement in the interconnect stretchability using Indium over the state-of-the-art without affecting the system performance. This was achieved without the necessity of the serpentine interconnects geometry that significantly improves the routing density. The manufacturing method used for this approach is also described. Finally, we discuss the cost competitiveness of the materials and the manufacturing method to assess the commercial viability of this approach. (5nm)

Original Configuration

Next-generation flexible electronics require highly stretchable and transparent electrodes. Few electronic conductors are both transparent and stretchable, and even fewer can be cyclically stretched to a large strain without causing fatigue. Fatigue, which is often an issue of strained materials causing failure at low strain levels of cyclic loading, is detrimental to materials under repeated loads in practical applications. Here we show that optimizing topology and/or tuning adhesion of metal nanomeshes can significantly improve stretchability and eliminate strain fatigue. The ligaments in an Au nanomesh on a slippery substrate can locally shift to relax stress upon stretching and return to the original configuration when stress is removed. The Au nanomesh keeps a low sheet resistance and high transparency, comparable to those of strain-free indium tin oxide films, when the nanomesh is stretched to a strain of 300%, or shows no fatigue after 50,000 stretches to a strain up to 150%. Moreover, the Au nanomesh is biocompatible and penetrable to biomacromolecules in fluid. The superstretchable transparent conductors are highly desirable for stretchable photoelectronics, electronic skins, and implantable electronics.

ABSTRACTFlexible electronics has emerged as a very promising field, in particular,wearable, bendable, and stretchable strain sensors with high sensitivity which could be used for human motion detection, sports performance monitoring, etc. In this paper, a highly stretchable and sensitive strain sensor composed of reduced graphene oxide foam and elastomer composite is fabricated by assembly and followed by a polymer immersing process. The strain sensor has demonstrated high stretchability and sensitivity. Furthermore, the device was employed for gauging muscle-induced strain which results in high sensitivity and reproducibility. The developed strain sensors showed great application potential in fields of biomechanical systems.
