Au Nanoparticles Doped Polyaniline Nanofiber Non-Volatile Memory Device

Tech ID: 24631 / UC Case 2004-561-0

Innovation

Professor Yang and colleagues have developed a solution-processable, polymer non-volatile memory storage device. The conductivity of the polymer material can be increased or decreased by applying a positive or negative voltage pulse, respectively, with an on/off conductivity ratio of 10^3. On/off ratios are expected to be maintained at 10^2-3 after 10^6 switching cycles, which is comparable to Si-based solid-state storage. The flexibility and low-cost manufacturing of the device allow for use in smart textiles, ID cards, RFID devices, and disposable electronics.
