Abstract
Selenium (Se), as an intriguing chalcogenide semiconductor, has traditionally been used for solar energy
harvesting. The recent development of nanoscience and nanotechnology has enabled a myriad of Se nanomaterials
with compelling structures and unique features. Compared with other chalcogens, Se nanomaterials possess
anisotropic crystalline structure, intrinsic chirality, and high reactivity, as well as unique optical, electrical,
photoconductive, and piezoelectrical properties. The integration of these Se nanomaterials with technologically
important materials, such as conductors and semiconductors, over flexible, bendable, stretchable, and highly
curved substrates offer a new generation of Se nanomaterial-based flexible and wearable electronics. In this mini
review, we survey the recent scientific and technological breakthroughs in Se nanomaterials-enabled flexible and
wearable electronics. We highlight the synthesis, fabrication, morphologies, structure, and properties (optical,
electrical, optoelectrical, photovoltaic, and piezoelectric) of Se nanomaterials as well as their integration into
innovative functional devices that deliver higher forms of applications across smart sensing, health care, and
energy domains. We conclude with a critical analysis of existing challenges and opportunities that will trigger the
continued progress of the field.
