Topic: UFTE

Silicon electrode arrays with thousands of channels enable read-out of the activity of large populations of neurons, but they induce chronic inflammation in the brain and a decline in signal quality. On the other hand, existing flexible electrode arrays have limitations on how reliably they can be inserted into any targeted depth in the brain while maintaining a high density of recording channels. To address these problems, we developed Ultra-Flexible Tentacle Electrodes (UFTE), where each recording channel is mechanically independent to provide maximal compliance with brain tissue—while also
