Ultra‐Lightweight Resistive Switching Memory Devices Based on Silk Fibroin

Ultra-lightweight resistive switching memory based on protein has been demonstrated. The memory foil is 0.4 mg cm−2, which is 320-fold lighter than silicon substrate, 20-fold lighter than office paper and can be sustained by a human hair. Additionally, high resistance OFF/ON ratio of 105, retention time of 104 s, and excellent flexibility (bending radius of 800 μm) have been achieved.
