Abstract
Applied Physics The properties of the human sense of touch, including high sensitivity to differences in temperature, pressure, or surface roughness, are challenging to replicate in robotics because skin materials must be highly conductive, stretchable, and thin. Jung et al. developed a process to assemble nanomaterials as a monolayer that is partially embedded in an ultra-thin elastomer. The process works by depositing a mixed solvent containing nanostructured silver and/or gold, along with elastomer, onto deionized water. This results in a layer of nanoparticles residing at the interface coating with elastomer, which is further densified by the addition of surfactant. The process is scalable, and the resulting elastomer membranes can be transferred to other substrates. Science , abh4357, this issue p. [1022][1] [1]: /lookup/doi/10.1126/science.abh4357
