  • Title: Hydrogel Actuators and Sensors for Biomedical Soft Robots: Brief Overview with Impending Challenges.
    Author: Banerjee H, Suhail M, Ren H.
    Journal: Biomimetics (Basel); 2018 Jul 10; 3(3):. PubMed ID: 31105237.
    Abstract:
    There are numerous developments taking place in the field of biorobotics, and one such recent breakthrough is the implementation of soft robots-a pathway to mimic nature's organic parts for research purposes and in minimally invasive surgeries as a result of their shape-morphing and adaptable features. Hydrogels (biocompatible, biodegradable materials that are used in designing soft robots and sensor integration), have come into demand because of their beneficial properties, such as high water content, flexibility, and multi-faceted advantages particularly in targeted drug delivery, surgery and biorobotics. We illustrate in this review article the different types of biomedical sensors and actuators for which a hydrogel acts as an active primary material, and we elucidate their limitations and the future scope of this material in the nexus of similar biomedical avenues.
