Minimally invasive, large-area ECoG arrays enabled by soft fluidic actuation. i) Illustration of the device's working mechanism: folded for implantation through a burr-hole craniotomy, followed by in situ expansion for large-area coverage. ii) Photograph of the fabricated thin-film device before folding. iii) In vivo validation on a porcine cortex, with craniotomy for implantation and X-ray images showing device deployment (outlined in white boxes).
