TL;DR: It is shown that an ultrathin, leakage-free, biocompatible dielectric layer can completely seal an underlying layer of flexible electronics while allowing for electrophysiological measurements through capacitive coupling between tissue and the electronics, and thus without the need for direct metal contact.

TL;DR: A solution to this materials challenge that combines ultrathin, pristine layers of silicon dioxide (SiO2) thermally grown on device-grade silicon wafers, and processing schemes that allow integration of these materials onto flexible electronic platforms is introduced.

TL;DR: A scalable neural interface technology projected to last at least 6 years in the body samples over a thousand brain sites using flexible electronics and provides stable in vivo neural recordings in rodents and nonhuman primates.

TL;DR: This work establishes the engineering science of categories of biointegrated microsystems that include assemblies of tens of thousands of microdevices interconnected into functional networks on thin flexible polymer substrates with areas that approach those of the human brain.

TL;DR: It is shown that µECoG arrays can reliably perform in chronic applications in vivo for over one year, which facilitates the development of a high-density, clinically viable interface.
