Abstract: With the continuous progress of information technology such as artificial intelligence and big data, bionic intelligent tactile perception technology has rapidly developed and led to remarkable progress in human-machine interface, bionic robotics, and other fields. As an important part, flexible bionic tactile devices have received wide attention in recent years due to their outstanding compatibility with living organisms in terms of physical form. By mimicking biological skin, flexible tactile sensors with different structures and functions, also called electronic skins, have been developed to achieve tactile sensing functions. However, with the increase of data volume, traditional flexible tactile sensors based on Von Neumann architecture face the bottleneck of power consumption and energy efficiency, which cannot adapt to the future development trend of low-power and intelligent sensing. Benefit from the highly parallel network structure of the biological neural network and its event-triggered computing mode, the biological sensory system realizes the perception and processing of external signals at a lower cost of space, time and power, and realizes the function of information processing and memory by synaptic weight modulation. Inspired from the biological sensory system, emerging flexible artificial neuromorphic sensory systems containing synaptic devices have been considered as a promising solution for processing massive data with low power consumption. In this paper, we reviewed recent developments in flexible bionic tactile devices and systems, both from bionic electronic skin tactile sensors to artificial synaptic device-based neuromorphic tactile sensing systems. Besides, key challenges and opportunities related to the construction of flexible artificial perception systems are examined, and potential solutions and suggestions are provided.
