Bio-Cellulose Substrate for Fabricating Fully Biodegradable Resistive Random Access Devices
Organic resistive random access memory (RRAM) has high potential in the nonvolatile memory field for next-generation green electronics. In general, RRAM devices are usually fabricated on substrates, for example, glass and plastic. In the present study, an Al/gelatin/Ag sandwiched structure on a bio-...

| description | Organic resistive random access memory (RRAM) has high potential in the nonvolatile memory field for next-generation green electronics. In general, RRAM devices are usually fabricated on substrates, for example, glass and plastic. In the present study, an Al/gelatin/Ag sandwiched structure on a bio-cellulose (BC) film is demonstrated, whose texture is flexible, ductile, and can be adapted to uneven surfaces. The BC film could be degraded completely in soil in only 5 days. In addition, the gelatin dielectric layer and the BC film substrate are non-toxic and environmentally friendly, realizing a skin-inspired and fully biodegradable device. This Al/gelatin/Ag/BC device shows a high on/off current ratio (>104), low operation voltage ( |
