Periodic Reporting for period 4 - SmartCore (Smart Core/shell nanorod arrays for artificial skin)
Période du rapport: 2021-06-01 au 2022-11-30
Such skin, applied to advanced robot could revolutionize the interaction between humans and machines, making the latter smarter, more responsive, safer and more human friendly.
We demonstrated that we can deposit ZnO by plasma enhanced atomic layer deposition at room temperature. The ability to grow inorganic thin films with highly controllable structural and optical properties at low substrate temperature enables the manufacturing of functional devices on thermo-sensitive substrates without the need of material postprocessing. The piezoelectrical properties of ultra thin ZnO films were studied for the first time by our group. We demonstrated that the piezoelectric coefficient depends on the growth temperature of the ZnO layer and on the substrate where it was deposited.
Regarding the complete artificial skin device, comprised of ZnO and the hydrogel, we -for the first time- created a device that shows multi responsiveness at high resolution.
