  • Download Movie_S01 (AVI) - Free-standing 128-channel mesh electronics in aqueous solution. This video shows seven free-standing 128-channel mesh electronics with the design shown in Fig. 1B, III suspended in water. Manipulation of the mesh electronics using a glass needle demonstrates their robustness of ultraflexibility. The frame rate is 25 frames per second (fps), and the video is played at 1× real time.
  • Download Movie_S02 (AVI) - Chronic recordings from a freely behaving mouse with implanted 32-channel mesh electronics probe. This video shows a mouse with a head-mounted voltage amplifier roaming freely in a cage with randomly positioned food pellets during recording. The frame rate is 25 fps, and the video is played at 1× real time. The mesh electronics were injected into the hippocampus with electrodes spanning across the hippocampal CA1 and CA3 fields and somatosensory cortex, and connected to PCB and the interface cable as described in Materials and Methods and SI Text.
