Albumen Based Flexible Memory Device for Bio-Sustainable Electronics

A flexible resistive memory device with natural albumen from eggs as a dielectric layer is demonstrated. These Ag/Albumen/ITO RRRAM devices have shown excellent resistive switching with high current on/off ratio of around 10
⁴
and memory retention time of 10
³
s without showing relevant degradation for pristine state. Moreover, devices have maintained the memory characteristics even after being bent at 7.5 mm radius, indicating that egg-albumen can be a promising candidate for bio-sustainable flexible memory devices.
