Implantable neuroelectronics constructed by biodegradable materials. (a) Right: schematic exploded-view illustration of the construction of a passive, bioresorbable neural electrode array for electrocorticography (ECoG) and subdermal electroencephalography measurements. Left: photographs of bioresorbable neural electrode arrays with four channels (top) and 256 (16 × 16 configuration) channels (bottom) (NMs, nanomembranes). Adapted with permission from Reference 22. (b) Schematic exploded illustration of a biodegradable, self-electrified, and miniaturized conduit device for sciatic nerve regeneration. Adapted with permission from Reference 23. (c) Images of dissolution of a bioresorbable wireless stimulator associated with immersion in phosphate-buffered saline (PBS) (pH 7.4) at 37°C. Adapted with permission from Reference 24.
