Towards All-Soft Matter Circuits: Prototypes of Quasi-Liquid Devices with Memristor Characteristics

A new class of memristors based entirely on soft and liquid‐based matter is presented. The devices are formed by interfacing liquid metal electrodes with water‐based gel doped with polyelectrolytes. They memorize the last state of bias polarization on the basis of the asymmetric conductance of the h...

description A new class of memristors based entirely on soft and liquid‐based matter is presented. The devices are formed by interfacing liquid metal electrodes with water‐based gel doped with polyelectrolytes. They memorize the last state of bias polarization on the basis of the asymmetric conductance of the hydrogel‐oxide‐liquid metal stack. Such devices may find application in circuit‐live tissue interfaces, soft robotics, and neuromorphic systems.
