Personalized Medical Devices Connect Monitoring and Assistance: Emerging Wearable Soft Robotics

“…However, most emerging strain sensors suffer from insufficient strength and conductivity, small sensitivity, weak interference immunity, and deficient functions for some specific applications. 68 Pressure Sensing. For the surface that can undergo elastic deformation, the external contact force will produce extrusion.…”

“…When soft grippers grasp cups of different sizes or when humanoid fingers make different gestures, the strain sensor can give corresponding feedback, paving the way for accurate control of the actuator system and human–computer safety interaction. However, most emerging strain sensors suffer from insufficient strength and conductivity, small sensitivity, weak interference immunity, and deficient functions for some specific applications …”

Polyacrylamide–Poly(vinyl alcohol)–Sodium Alginate–Reduced Graphene Oxide/Nylon Fabrics with Multistimuli Responses

“…Meeting these aforementioned requirements often requires the combination of fabrics with various materials possessing distinct properties.

“…Meeting these aforementioned requirements often requires the combination of fabrics with various materials possessing distinct properties. Recently, conductive materials have been used to compound with fabrics to realize various sensing functions, and the conductive materials reported include metals and their derivatives, , conductive polymers, , liquid electrodes, and so on. Among these materials, conductive hydrogels have been most commonly used because of their superior biocompatibility and comfort. , However, many of the existing functional fabrics have been found only responding to few stimuli or only suited to few wearable scenarios. − Therefore, this inability to simultaneously achieve multistimuli responses and diversified wearable application scenarios highlights a critical need to expand both multistimuli responses and multiapplication scenarios for these functional fabrics.…”
