Implantable electronics have recently been attracting attention because of the promising advances in personalized healthcare. They can be used to diagnose and treat chronic diseases by monitoring applying bioelectrical signals various organs. However, there are challenges regarding rigidity hardness typical electronic devices that trigger inflammatory reactions tissues. In an effort improve physicochemical properties conventional implantable electronics, soft hydrogel-based platforms emerged...
Realization of interactive human-machine interfaces (iHMI) is improved with development soft tissue-like strain sensors beyond hard robotic exosuits, potentially allowing cognitive behavior therapy and physical rehabilitation for patients brain disorders. Here, this study reports on a strain-sensitive granular adhesive inspired by the core-shell architectures natural basil seeds iHMI as well human-metaverse interfacing. The sensor consists easily fragmented hydropellets core tissue-adhesive...
Conductive hydrogels are promising materials in bioelectronics that ensure a tissue-like soft modulus and re-enact the electrophysiological function of damaged tissues. However, recent approaches to fabricating conductive have proved difficult: fixing on target tissues requires aids from other medical glues because their weak tissue-adhesiveness. In this study, an intrinsically tissue-adhesive granular hydrogel consisting PEDOT:PSS conducting polymer adhesive catechol-conjugated alginate was...
Hydrogels that have a capability to provide mechanical modulus matching between time-dynamic curvilinear tissues and bioelectronic devices been considered tissue-interfacing ionic materials for stably sensing physiological signals delivering feedback actuation in skin-inspired healthcare systems. These functionalities are totally different from those of elastomers with low conductivity higher stiffness. Despite such remarkable progress, their remains limited transporting electrical charges...
Stretchable MED-ET was fabricated by a soaking process of self-healing stretchable Ag ink. Conductive pathways in under damaged environment were stably maintained due to an electrical recovery phenomenon which enables robust device system.
Soft bioelectronic systems with a unique mechanical property, namely modulus matching between human skin (or tissue) and the device, have gained widespread attention. This is because of their closed-loop strain-insensitive electrical performance ranging from application in long-term stable measurements physiological signals feedback modulation to organs). Various materials integration/fabrication strategies such as buckled, rigid islands, wavy designs addressed for soft require complex...
Laundering is essential for maintaining personal hygiene but can lead to fabric damage, such as color fading and fiber loss, caused by frequent excessive mechanical action. Front-loading washers utilize force falling, rotating, sliding remove soil from textiles, where properties influence these movements, resulting in varied actions depending on type. Herein, the relationship between movement pertaining action was analyzed, focusing correlated movements motor torque current parameters. The...
