Full device next to quarter for scale

Caption

One version of the device covered 91% of an organoid’s surface and incorporated 240 individually addressable microelectrodes. Because organoids are often just a millimeter in diameter, the engineers had to push the size of the electrodes to the extreme. They developed highly miniaturized electrodes, measuring just 10 microns in diameter — about the size of an individual cell.
