Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

open access: yesAdvanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.
