Recent advances in electronic skins: material progress and applications

Abstract

Electronic skins are currently in huge demand for health monitoring platforms and personalized medicine applications. To ensure safe monitoring for long-term periods, high-performance electronic skins that are softly interfaced with biological tissues are required. Stretchability, self-healing behavior, and biocompatibility of the materials will ensure the future application of electronic skins in biomedical engineering. This mini-review highlights recent advances in mechanically active materials and structural designs for electronic skins, which have been used successfully in these contexts. Firstly, the structural and biomechanical characteristics of biological skins are described and compared with those of artificial electronic skins. Thereafter, a wide variety of processing techniques for stretchable materials are reviewed, including geometric engineering and acquiring intrinsic stretchability. Then, different types of self-healing materials and their applications in electronic skins are critically assessed and compared. Finally, the mini-review is concluded with a discussion on remaining challenges and future opportunities for materials and biomedical research.

Rugged Island-Bridge Inorganic Electronics Mounted on Locally Strain-Isolated Substrates

“…Despite the potential reduction in stretchability due to the integration of rigid islands within the stretchable polymer, our hybrid system exhibits exceptional stretchability and durability. It consistently maintains a strain of over 50% in cycle tests (Figures g–i, S13, S15, and S16), exceeding the required strain threshold for stretchable electronics applications. − …”

Researchers at RMIT University in Australia (Rahman et al, 2020) have developed a new electronic skin by combining three technologies previously pioneered and patented by the team: stretchable electronics, self-modifying coatings, and electronic memory cells.…”

PAA‐PU Janus Hydrogels Stabilized by Janus Particles and its Interfacial Performance During Hemostatic Processing

“…Uncontrollable bleeding after trauma or during surgery is the leading cause of death. [ 1 ] According to the literature, when the human body suffers from severe trauma, it cannot rapidly stop bleeding by relying on its own body's intrinsic coagulation alone. [ 2,3 ] Heavy bleeding will cause metabolic and cellular dysfunction, which will lead to insufficient oxygen delivery to the tissues, and ultimately lead to hemodynamic instability, hypoxemia, multi‐organ failure, tissue necrosis, shock, and even death.…”
