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.

“…In Figure 3f, inspired by the art of Kirigami, Guo et al. [ 168 ] were able to turn 2D film‐shaped TEGs into deformable and stretchable 3D TEGs by subtly introducing Kirigami cuts into the flexible substrate. The kirigami structure on polyimide covers a series of alternately arranged linear patterns arranged alternately using laser cuts.…”

“…It is worth mentioning that TEGs with flexible substrate outperform TEGs with rigid substrate in numerous aspects for their flexibility, thus enabling them to conform to any surface of the human body. [ 102,108–110,165–177 ] For yarn‐shaped TEGs, organic materials have been predominantly used as thermoelectric materials (e.g., PEDOT: PSS and CNTs). Yarn‐shaped TEGs are extremely flexible and stable, thus easily adhering to the heat source.…”

Considerable thermal energy is emitted into the environment from human activities and equipment operation in the course of daily production. Accordingly, the use of thermoelectric generators (TEGs) can attract wide interest, and it shows high potential in reducing energy waste and increasing energy recovery rates. Notably, TEGs have aroused rising attention and been significantly boosted over the past few years, as the energy crisis has worsened. The reason for their progress is that thermoelectric generators can be easily attached to the surface of a heat source, converting heat energy directly into electricity in a stable and continuous manner. In this review, applications in wearable devices, and everyday life are reviewed according to the type of structure of TEGs. Meanwhile, the latest progress of TEGs’ hybridization with triboelectric nanogenerator (TENG), piezoelectric nanogenerator (PENG), and photovoltaic effect is introduced. Moreover, prospects and suggestions for subsequent research work are proposed. This review suggests that hybridization of energy harvesting, and flexible high‐temperature thermoelectric generators are the future trends.

“…Soft bridges do not necessarily affiliate with rigid islands, as they could independently form flexible devices such as stretchable conductors, antennae, strain sensors, [ 87,107,108 ] etc. Diverse structure configurations of soft bridges have been proposed, including wavy structures, [ 46,47,50,85,109,110 ] origami, [ 111,112 ] kirigami, [ 90,113–115 ] 2D spiral, [ 86,116,117 ] 3D helical forms, [ 118 ] etc. All these structures accommodate strain by bringing in extra dimensions, i.e., in‐plane bending, out‐of‐plane buckling, etc.…”

Stretchable electronics possess significant advantages over their conventional rigid counterparts and boost game‐changing applications such as bioelectronics, flexible displays, wearable health monitors, etc. It is, nevertheless, a formidable task to impart stretchability to brittle electronic materials such as silicon. This review provides a concise but critical discussion of the prevailing structural engineering strategies for achieving strain‐tolerant electronic devices. Not only the more commonly discussed lateral designs of structures such as island‐bridge, wavy structures, fractals, and kirigami, but also the less discussed vertical architectures such as strain isolation and elastoplastic principle are reviewed. Future opportunities are envisaged at the end of the paper.
