Memristor-integrated sensing systems leveraging quantum conductance effect for artificial bioelectronics

The application of memristive devices in the field of bionics is widespread, as they possess rapid operational speed, a straightforward device structure, and high density, enabling them to effectively mimic sensing, memory, and computing functions. Herein, the memristor-integrated sensing system is a new concept that has been proposed by researchers in recent years. In this review, we provide a comprehensive summary of recent advancements in smart memristive materials and devices for sensing various physical stimuli, such as electricity, magnetism, force, light, heat, and other properties. Additionally, we discuss the integration of digital memristors into sensing systems via thin-film or micro/nano-devices, as well as the integrated technology of in-sensor computing. The popular artificial bionic sensing systems based on memristors are also introduced, including artificial synapses and neuromorphic computing, biomimetic eye and artificial vision, artificial olfactory and gustatory systems, as well as health monitoring systems. The challenges and prospects of this innovative topic are finally expounded, aiming to provide a more comprehensive and up-to-date understanding of the subject matter, as well as identifying potential areas for future research and practice.
