In animal studies, 2 µm-thick silicon-based films were successfully printed onto the surfaces of nerves and brains, forming conformal bioelectronic interfaces. Using these interfaces, infrared light was able to induce periodic limb movements in the animals, demonstrating precise spatiotemporal control of the neural activity. This work provides new insight into the damage-free attachment of ultrathin films onto complex three-dimensional surfaces by dynamically releasing stress during conformal deformation.
