Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications
Advanced Materials Technologies, EarlyView.Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators
Advanced Science, EarlyView.This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.
