摘　　要：Self-rectifying memristor(SRM)arrays hold tremendous potential in high-density data storage and energy efficient neuromorphic computing.However,SRM arrays are mostly developed on rigid substrates and lack mechanical flexibility,limiting their applications in intelligent electronic skin,wearable technologies,etc.Here,we present a high performance SRM array based on Pt/HfO_(2)/Ta_(2)O_(5−x)/Ti heterojunctions,which can be fabricated on a flexible polyimides(PI)substrate and demonstrates exceptional memristive performance under bending conditions(bending radius(R)=1 cm,rectifying ratio>10^(4),retention time>10^(4) s and endurance>105 cycles).We demonstrate a 16×16 flexible memristor array offering noise filtering and data storage capabilities,which can be used to accurately process and store the signals transmitted by a pressure sensor array.This research represents an important advancement towards the realization of next-generation high-performance flexible electronics.
