Stretchable Interconnects: Materials, Geometry, Fabrication, and Applications

In recent days, stretchable devices gained utmost importance due to their stretchable, bendable, flexible characteristics and also their comfort toward human skin. Stretchable materials are undeniable compared to conventional materials due to its ability to adjust to the curvilinear surface of human skin. When stress or strain is applied it maintains its electrical functionality which is useful for stretchable electronics devices. Stretchable interconnect plays a vital role in these modern stretchable devices by providing an extra degree of stretchability. This survey chapter presents an overview of stretchable interconnect geometries, fabrication techniques, and materials used to fabricate substrate materials. In addition, a wide range of applications are discussed such as strain sensor, temperature sensor, and energy harvesters. The key developments of stretchable interconnects have been highlighted in the domains of healthcare monitoring and energy storage devices.
