The project “Smart Core/shell nanorods arrays for artificial skin” (Acronym: Smart Core, Number:715403) aims at integrating temperature and humidity together with pressure sensing in a single novel hybrid material. An array of stimuli-responsive nanorods is created on a surface to fabricate an efficient device for artificial skin applications. The nanorods have a core-shell structure comprised of a multi-stimuli-responsive smart material and a piezoelectric ZnO shell. The stimuli coming from the environment, such as humidity or temperature changes, will be sensed by the smart material, inducing changes in size and shape. The changes in shape and size of the core will be detected by the ZnO shell and transformed in measurable voltage pulses, thanks to the piezoelectric properties of the ZnO. More info are included in the results in brief page of CORDIS.
