Dual‐Mode Gripper With Suction and Shape‐Adaptive Freezing Grasps
Advanced Robotics Research, EarlyView.This study presents a dual‐mode robotic gripper that combines vacuum suction with a shape‐adaptive freezing grasp. The freezing mode uses a compliant rubber membrane, a sprayed water layer, and dry‐ice powder to generate ice‐mediated adhesion while conforming to complex geometries.

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management
Advanced Science, EarlyView.A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...
