Researchers have developed a sunlight-activated nanospray that can rapidly kill drug-resistant bacteria, stop bleeding and relieve pain, significantly accelerating the healing of infected diabetic wounds. The technology works under natural sunlight without the need for complex equipment or antibiotics, offering a safer and more accessible treatment option for chronic wounds.

Soft actuation remains the key bottleneck in creating soft robots with flexible deformation and agile locomotion similar to nature creatures. Despite extensive efforts, it remains performance trade-offs among speed, strain, force, and portability of auxiliary equipment for existing soft actuators, thus also presents significant challenges for developing untethered soft robots with high mobility. Recently, researchers from Tongji University report a new concept of electrohydraulic origami which combines the transmission and reconfiguration of compliant origami structures with high dynamic soft electrohydraulic actuation to create powerful, programmable and multimodal soft actuators. The resulting lightweight, compliant, scalable, and reconfigurable electrohydraulic origami actuators open up a new way for building and actuating soft robots with fast, agile, and multimodal locomotion.
