Syringe-injectable mesh electronics with plug-and-play interface. (A) Schematic diagram of the plug-and-play mesh electronics, where the ultraflexible recording region (green box; lower left inset, zoom) converges to a flexible stem terminating in mesh metal I/O pads perpendicular to the stem (blue box; lower right inset, zoom). The stem and mesh I/O remain outside the skull. (B) Schematic diagram of direct clamping of the mesh I/O pads into a PCB-mounted ZIF connector (red arrow), which can then be connected to measurement electronics via a standard Omnetics connector (yellow arrow) mounted on the same PCB. (C) Photograph showing electrophysiological recording of a freely moving mouse injected with mesh electronics; the inset shows the part of the interface that remains permanently attached to the mouse head without the amplifier and the cable connected.
