A new approach to making transistors will involve depositing sequentially their components in the form of liquid nanocrystal â€œinksâ€ say researchers at the University of Pennsylvania. The research could lead to flexible electrical components that might be used in wearable devices and other applications. The lower-temperature process makes the possibility of embedding such components in a wide variety of materials as well as making large area devices. According to Cherie Kagan and colleagues the nanocrystal-based field effect transistors were patterned on to flexible plastic supports using spin coating but could be amenable to additive manufacturing systems, such as 3D printing.
