Materials (ISSN: 1996-1944) has launched the Section “Smart Materials”. This Section is a forum for the rapid publication of works pertaining to the preparation, characterization, and application of all smart materials. The scope of smart materials comprises, without being limited to, various applications in sensors and actuators, soft robotics, wearable electronics, flexible/stretchable electronics, energy generation and storage devices, displays, and shape memory polymers by utilizing the concept of smart materials.

We are pleased to present the 2022 Editor’s Choice Articles, which is a carefully curated list of high-quality articles from the Section “Smart Materials”.
