In this study, we demonstrate how atomically dispersed ionic platinum (Pt2 +) on
ceria (CeO2), which is already thermally stable, can be activated
via steam treatment (at 750 °C) to simultaneously achieve the goals of low - temperature carbon monoxide (CO) oxidation activity while providing outstanding hydrothermal stability.
Corresponding electrical stimuli can then be transmitted from the prosthetic skin to the body to stimulate peripheral nerves
via an ultrathin multi-electrode array, which is decorated with
ceria nanoparticles for inflammation control.
