Self‐Powered and Imperceptible Electronic Tattoos Based on Silk Protein Nanofiber and Carbon Nanotubes for Human–Machine Interfaces (Adv. Energy Mater. 29/2021)

Human–Machine Interfaces In article number 2100801, Narendar Gogurla and Sunghwan Kim design an energy tattoo system by printing carbon nanotube electrodes on a silk protein nanofiber mat that can be imperceptibly interfaced with human skin. Each individual element on the skin acts as a primary interacting device for human-machine interfaces to read the tactile movements of a fingertip through triboelectric phenomena.
