Particle-armored liquid robots (PBs) are millimetric soft robots made of water droplets coated in abundant superhydrophobic PTFE (Polytetrafluoroethylene / Teflon) particles, mimicking cell-like deformability and resilience. Developed by researchers at Seoul National University, they outperform traditional liquid marbles by using cuboid ice molds to boost particle coverage by 59%, achieving an optimal aspect ratio of 1.55 for maximum strength.
