Don’t dive in, wade through it
A new “shapeshifting” liquid metal pump uses a droplet that splits and fuses itself to push fluid—running on millivolts and a tiny magnet. The result is a soft, silent, wrist-wearable pump that outperforms many micro-pumps and could power soft robots, smart clothing, and lab-on-a-chip devices.
A rewritable, acoustically transparent polymer film paired with a compact piezo array turns ultrasound into dynamic holograms—10,000 px/cm² and 50,000 fps. The system preserves energy, writes heat paths through tissue, and herds microparticles on demand. It’s a leap toward real-time acoustic tweezers, precise therapy, and reconfigurable micro-assembly.
Engineers can now 3D-print “slippery” architectures that lock in a nano-thin oil layer, guiding droplets without pumps. The method is transparent, scalable, and anti-fouling—perfect for diagnostics, anti-icing optics, and clean tools.
