Miniature Liquid‑Metal Pump Enables New Capabilities for Soft Robotics

Researchers have unveiled a tiny pump that uses liquid metal to power soft robotic actuators. The device measures only a few millimeters across, yet can generate significant force. Its liquid‑metal core provides rapid, reversible deformation without traditional valves. The pump operates at low voltage, making it compatible with portable power sources. Engineers anticipate applications in medical devices, wearable exosuits and micro‑manipulators. The technology addresses previous limitations in size and responsiveness of soft actuators. Early prototypes have demonstrated smooth, repeatable motion in laboratory tests. Commercial development will focus on scaling production and integrating the pump into robotic systems.
