Review compares muscle-stimulation methods for biohybrid robots
What the study found This review says prior studies on muscle-driven biohybrid robots for walking and crawling can be organized by three muscle-stimulation techniques: electrical field, optical, and neuromuscular junction-based stimulation. It also describes different walker and crawler models, their design principles, and their operating mechanisms. Why the authors say this matters The authors say…
Dual-network hydrogel ionic diode shows high current rectification
—
in EngineeringWhat the study found The study reports a dual-network hydrogel-based ionic diode that achieved a very high current rectification ratio of 53.9. The hydrogel combines polyvinyl alcohol and polyacrylamide matrices with cationic polydiallyldimethylammonium and anionic poly(sodium 4-styrenesulfonate) polyelectrolytes. Why the authors say this matters The authors say ionic diodes are of interest for flexible electronics…
