Partially actuating soft gripper based on multi-channel dielectric elastomer actuator

본 연구에서는 독립적으로 작동이 가능한 여러 개의 채널을 가지는 다층의 유전탄성체 액추에이터를 활용해서 낮은 전압에서의 변형이 가능하며, 독립적인 채널의 작동을 통해서 폭을 자유자재로 조절이 가능하다는 것을 보여줄 수 있다. 이러한 특성을 바탕으로 해서 다양한 물체들을 집는 것이 가능함을 보여줄 수 있고, 작동 가능한 채널을 조합해서 쌓아둔 물체를 선택적으로 집는 것이 가능함을 보여줄 수 있다.

Geometry‐Encoded Soft Strain Sensing via Liquid‐Metal Transmission Lines

Advanced Science, EarlyView.
This study presents a liquid‐metal transmission‐line strain sensor that achieves intrinsic decoupling by encoding axial elongation into propagation delay. The time‐domain readout remains stable under complex off‐axis. This enables reliable, repeatable, real‐time elongation measurement in dynamic, multiaxial loading environments for wearable electronics,
