Flexible data storage based on organic nanomaterials

Mon, 04/09/2018 - 12:36
Next-generation electronic devices will be highly portable, wearable - even transplantable - lightweight, and most likely self-powered. Among the various functional block required for these systems (such as displays, sensors, actuators, etc), some of the most important components are novel flexible data storage systems that possess nonvolatile ability, high-density storage, high-switching speed, and reliable endurance properties. Especially organic memories have been considered as the most promising candidates to be used in various portable and wearable systems in future due to their remarkable advantages of nonvolatile memory features, low cost, easy fabrication, and flexibility.
