Biocompatible Sensors: Biocompatible Soft Fluidic Strain and Force Sensors for Wearable Devices (Adv. Funct. Mater. 7/2019)

Abstract

In article number https://doi.org/10.1002/adfm.201807058, Robert J. Wood and co‐workers describe a silicone‐based strain and force sensor composed of a novel biocompatible conductive liquid (potassium iodide and glycerol solution). This solution is not only safe to the human body, but also has higher conductivity and lower viscosity compared to previously used biocompatible liquids.

Advances in Materials for Soft Stretchable Conductors and Their Behavior under Mechanical Deformation

“…For instance, silicone-based sensors composed of biocompatible conductive liquid, potassium iodide and glycerol (KI-Gly), are introduced by Xu et al for strain and force detection. These sensors exhibit low hysteresis along with high linearity and report GF of 2.2 [234]. These performance metrics suggest high electromechanical coupling between the ionic fluid and the hydrogel substrate.…”

Ti2C3Tx/Polyurethane Constructed by Gas–Liquid Interface Self-Assembly for Underwater Sensing

“…With the development of electronic information and Internet of Things technology, various sensors have been integrated into our daily life to facilitate effective and convenient information collection, such as electronic skins, , electronic tattoos, , and smart masks. , However, in practical applications, the human body inevitably bends and stretches, which causes the sensor to become uncomfortable to wear and easy to fall off. Flexible electronics − have provoked much attention due to their softness, high elasticity, comfort to wear, foldability, etc., exhibiting an outstanding potential in the fields of motion monitoring, − human-interactive systems, , medical diagnosis, , and artificial intelligence. , Therefore, the development of flexible materials and sensors has become a hot topic in the research community.…”

Electrochemical Dual Transducer for Fluidic Self-Sensing Actuation

“…Soft robots have a wide range of applications, including mobility and exploration, manipulation, medical and surgical applications, rehabilitation, and wearable robots . Many soft robots employ fluidic systems, which offer versatility, robustness, and ease of fabrication. − Previous studies have examined fluidic systems, a pump-driven flexible display, a soft pneumatic actuator, a soft fluidic sensor, a computing method by conductive and insulating liquids, and automated fabrication of flow channels by a 3D printer …”
