Flexible 3D penetrating microprobe array. a A schematic illustration of the flexible 3D penetrating microprobe array. The inset is an exploded structure of a single probe. b An optical image of 3D penetrating microprobe array on a curved surface. (scale bar, 2 mm). c An optical image of microprobes. (scale bar, 500 μm). d An optical microscopic image of a single microprobe. (scale bar, 500 μm)
