Recent efforts in the semiconductor industry have focused on the realization of electronics with unusual form factors and functions which are not achievable using the current planar Si-based technology. Deposition of high-quality films or nanomaterials on low-temperature elastomeric substrates has been a technical challenge for flexible electronics. However, together with the development of new synthesis routes that enable the formation of robust thin films and nanomaterials on compliant substrates, including the dry transfer printing technique and fabrication of uniform nanogaps/nanowrinkles using the unique stretchable characteristics of elastomeric substrates, flexible electronics has emerged as a promising technology that can enrich our lives in a variety of ways. As examples, potential applications include skin-like smart prostheses, paper-like displays, disposable electronic noses, and hemispherically-shaped electronic eye cameras. Here, we review recent results demonstrating ingenious new functionalities using nanomaterials on flexible substrates, focusing on fabrication techniques, materials, operation mechanisms, and signal outputs.
