Mechanically Durable Memristor Arrays Based on a Discrete Structure Design.
2021
Memristors constitute a promising functional component for information storage and in-memory computing in flexible and stretchable electronics including wearable devices, prosthetics and soft robotics. Despite tremendous efforts made to adapt conventional rigid memristors to flexible and stretchable scenarios, stretchable and mechanical damage endurable memristors have never been achieved, which is critical for maintaining reliable functions under unexpected mechanical attacks. Here, we reported the development of stretchable memristors with mechanical damage endurance based on a discreate structure design. Our memristors possess large stretchability (40%) and excellent deformability (half-fold), and retain stable performances under dynamic stretching and releasing. We show that our memristors maintain reliable functions and preserve information after extremely mechanical damages including punctures (up to 100 times) and serious torn situations (fully diagonal cut). Our structural strategy offers new opportunities for next-generation stretchable memristors with mechanical damage endurance, which is vital to achieve reliable functions for flexible and stretchable electronics even in extreme and highly dynamic environments.
