Deployable multilegged soft ECoG array using pressure-driven actuation. i) Image showing the device structure, consisting of the actuation component, strain sensor, and microelectrodes. ii) Top view of the ECoG array in its folded (top) and deployed (bottom) states, actuated by a positive fluidic pressure differential. iii) Deployment in a phantom brain model. The device is implanted through a 22 mm diameter burr hole, and then everted via fluidic pressure actuation.
