Extended Data Fig. 6: XCT images.

Reconstructed 3D XCT image (top left) of the RF electrode structure, with a horizontal slice (top right) and vertical slices (bottom row) through the electrodes. Bright regions denote the Au coating and colour scales represent the local coating thickness. The low atomic number polymer substrate is not detected, so only the metal layer appears.
