Multiresponsive Color‐Tunable Phosphorescence With Matrix‐Confined Clusters

open access: yesAggregate, EarlyView.
The molecule with cluster‐triggered emission mechanisms is embedded in polymer matrix, the phosphorescence properties of multiclusters are size‐dependent and exhibit different responses to various stimuli, including temperature, concentration, and excitation, which synergistically induce color‐range tunable time‐dependent phosphorescence color behavior.

Protective and Collision‐Sensitive Gel‐Skin: Visco‐Elastomeric Polyvinyl Chloride Gel Rapidly Detects Robot Collision by Breaking Electrical Charge Accumulation Stability

open access: yesAdvanced Intelligent Systems, EarlyView.
For safe human–robot collaboration (HRC), a protective and collision‐sensitive robot skin is proposed. The developed robot skin, named Gel‐Skin, is composed of polyvinyl chloride (PVC) gel, which is a functional material with impact absorption capability and tunable piezoresistive characteristics based on electrical charge‐accumulation.
