Key terms for readers.
EGaIn
Eutectic gallium-indium, a room-temperature liquid metal commonly used in soft electronics and stretchable conductors.
Oxide skin
A thin gallium oxide layer that stabilizes liquid-metal shapes but can also cause adhesion, residue, and contact resistance.
Phase-transitional matter
A material system that can switch between solid-like and liquid-like states for different mechanical tasks.
Liquid-metal embedded elastomer
A soft composite where liquid-metal droplets or networks are embedded inside stretchable polymer material.
TRL
Technology Readiness Level, a scale used to describe maturity from basic principles to operational deployment.
Magnetic actuation
Use of magnetic fields to move, heat, steer, or transform a material or robot.
