The nanoelectrodes are made of magnetoelectric materials, which means they work by converting a magnetic signal into an electric signal. So, we can wirelessly power them using a magnetic signal. (More beautiful artwork by Moritz).

We make wireless neural stimulators out of nanoparticles, or "nanoelectrodes". We can wirelessly power them to generate a local electric field. So, they can work like a very small, wireless bioelectronic, and be used to e.g. stimulate the brain. (Artwork by student Moritz Hocher shows the idea).
