The aqueous electrolyte can be a deformable and stretchable liquid material for
iontronic resistive memory devices. An aqueous medium makes a device closer to
the brain-like system with the movement of ions. This review paper proposes
advances in liquid resistive memories and neuromorphic computing behavior to
emulate electronic synapses. Primarily, the aqueous iontronic resistive memories
can be used to study electrode and active layer materials and different device
structures. Hence, herein, a timely and comprehensive study of these devices
using ionic liquids, hydrogels, salt solutions, and soft electrodes to classify the
device mechanism is presented. The filament formation is discussed in detail
based on ion concentration polarization, electrode metallization, and movements
of ions and charged molecules, which result in the formation of the metal
dendrite. To manufacture a higher-performance memory, device parameters
should be optimized based on aqueous electrolytes, electrode materials, and
other device design parameters. Aqueous electrolytes have smooth neurotransmission
ability to fabricate brain-inspired resistive memories with stable
performance and device repeatability with smooth ion transmission. Aqueous
electrode materials can be reliable for neural interface activities to compute
electronic synapsis with electrical and chemical properties to ensure device
reliability for a longer time period.
