Flexible Organic Memory Device Fabricated with Printing Method

We have developed novel ferroelectric materials with helical biopolymers such as polypeptides and DNA. Using the materials, a memory device of ferroelectric field-effect transistor was fabricated with a printing method. This technology will accelerate the development of all-printed fabrication of ubiquitous information terminal such as a flexible display.
