|Microelectrode arrays (MEAs) are devices that serve as neural interfaces, connecting neural signals to electronic circuitry. Current MEAs are not fabricated in a complementary metal-oxide semiconductor (CMOS) platform; therefore, they suffer from low yield and low sensitivity and require packaging to bring the lead out. The CMOS version of MEA is not flexible and still requires packaging.
Researchers at Purdue University have developed a highly-flexible microelectrode array built on a complementary metal oxide semiconductor chip that senses live cells, neurons, and live tissues. This technology not only improves the yield and sensitivity, it brings the advantages of CMOS integration, e.g., wireless link and wireless powering. It can be used on concave and pulsating and moving tissues and cells, such as a retina. The technology will make it possible to achieve a single-cell characterization platform, cochlea implant, wireless retina, neural recording devices, and nerve connectors to mend severed peripheral nerves.
