Advances in flexible sensors for intelligent perception system enhanced by artificial intelligence

Abstract

Intelligent perception means that with the assistance of artificial intelligence (AI)-motivated brain, flexible sensors achieve the ability of memory, learning, judgment, and reasoning about external information like the human brain. Due to the superiority of machine learning (ML) algorithms in data processing and intelligent recognition, intelligent perception systems possess the ability to match or even surpass human perception systems. However, the built-in flexible sensors in these systems need to work on dynamic and irregular surfaces, inevitably affecting the precision and fidelity of the acquired data. In recent years, the strategy of introducing the developed functional materials and innovative structures into flexible sensors has made some progress toward the above challenges, and with the blessing of ML algorithms, accurate perception and reasoning in various scenarios have been achieved. Here, the most representative functional materials and innovative structures for constructing flexible sensors are comprehensively reviewed, the research progress of intelligent perception systems based on flexible sensors and ML algorithms is further summarized, and the intersection of the two is expected to unlock new opportunities for next-stage AI development.
