Implantable electronics: A sensor web for neurons

An implantable, flexible mesh with embedded electrodes for sensing neural activity in vivo improves brain-sampling efficiency and reduces the amount of cortical tissue injured. If achieved, the implications are profound: neuroprosthetics could afford individuals the freedom to control the external environment with minimal effort just by thinking about it. Xie and colleagues describe a novel macroporous, flexible mesh probe for neural sensing that can be implanted in the brain with a minimal footprint.
