Sensors: Highly Sensitive and Multimodal All‐Carbon Skin Sensors Capable of Simultaneously Detecting Tactile and Biological Stimuli (Adv. Mater. 28/2015)

Abstract

A highly sensitive, wearable, and multimodal skin sensor is described by Y. Jeong, D. H. Kim, and co-workers on page 4178, using hierarchically engineered elastic carbon nanotube microyarns. Piezocapacitive all-carbon skin sensors simultaneously detect subtle heterogeneous external stimuli, including mechanical deformations, touch, temperature gradients, and even biological fluids, which enables in situ human monitoring, as well as recognition of a robot–human environmental interface.
