Artificial Skin: Microstructured Graphene Arrays for Highly Sensitive Flexible Tactile Sensors (Small 18/2014)

Abstract

Flexible tactile sensors with outstanding sensitivity in the low pressure regime are in demand for the development of artificial skin. On page 3625, X. Chen and co-workers devise a resistive tactile sensor using microstructured graphene arrays as sensitive layers. The introduction of the anisotropic microstructure arrays makes the sensor sensitive and fast to external pressure. It also shows a remarkable capability in information transmission, demonstrating great potential for application in human-machine interfaces.
