Beyond Human Touch Perception: An Adaptive Robotic Skin Based on Gallium Microgranules for Pressure Sensory Augmentation (Adv. Mater. 44/2022)

Abstract

Robotic Skin In article number 2204805, Jae-Woong Jeong and co-workers report an adaptive robotic skin with an augmented pressure-sensing capability beyond that of human skin. The robotic skin is composed of gallium microgranules fabricated uniformly using a T-junction microfluidic system. Through the phase transition of gallium microgranules, it achieves a higher sensitivity in the soft mode and a broader dynamic range in the rigid mode compared to human skin.
