Abstract

A highly sensitive, wearable, and multimodal skin sensor that uses hierarchically engineered elastic carbon nanotube microyarns is described. Piezocapacitive all-carbon skin sensors simultaneously detect heterogeneous external subtle stimuli, including mechanical deformation, touch, temperature or humidity gradients, and even biological variables with different dipole moments, which enables in situ human monitoring as well as recognition of robot-human-environmental interface. © 2015 WILEY-VCH Verlag GmbH & Co.
