Soft actuators offer several advantages over traditional rigid machines. Among soft materials, liquid metal (LM) is particularly noteworthy for its electro-responsive surface properties that induce flow or morphological changes, making it ideal for soft machines. Although using LM droplets as micropumps is simple, they face challenges in efficient vertical fluid pumping. Here, we report a pump-valve dual-functional LM soft actuator (PDLMA) that can continuously pump liquid upward. Benefiting from the unique conformability of LM, the PDLMA can provide the function of a check valve, which blocks...
Nanoengineering the composition and morphology of functional nanoparticles endows them to perform multiple tasks and functions. An intriguing strategy for creating multifunctional nanomaterials involves the construction of core–shell nanostructures, which have enabled promising applications in biomedicine, energy, sensing, and catalysis. Here, a straightforward nanoengineering approach is presented utilizing liquid metal nanoparticles and galvanic replacement to create diverse core–shell nanostructures. Controlled nanostructures including liquid metal core-gold nanoparticle shell (LM@Au), ...
Conductive hydrogels have been promising candidates for wearable and flexible electronics due to their high flexibility and biocompatibility. However, the previously reported hydrogels with conductivity over 1000 S m−1 usually have poor mechanical properties including low tensile stress (<5 >MPa) and toughness (<2 MJ>m−3). Here, a liquid metal-doped polyvinyl alcohol (PVA-LM) hydrogel is presented, which simultaneously combines ultra-high conductivity (maximum of 217 895 S m−1) with excellent mechanical properties, including high tensile stress (15.44 MPa), large tensile stra...
Liquid metals could be the long-awaited solution to “greening” the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineerin ...
