A recently granted patent (Publication Number: US11969250B2) discloses a brain electrode device designed to sense signals from the brain efficiently. The device includes a plurality of contact points, sub-circuits with sensor ports connecting to the contact points, and an intelligent multiplexer that aggregates signals from the sub-circuits to generate an aggregate signal. This aggregate signal is then transmitted to a signal acquisition device for further processing. The device also features sample/hold circuits for sampling input signals, a snapshot signal circuit to instruct the sample/hold circuits on timing, and a reset mechanism for the sample/hold circuits during the next snapshot pulse.

In addition to the brain electrode device, the patent also outlines a method for sensing signals from the brain. This method involves engaging an electrode array with the brain, sampling signals at the respective cells, aggregating the signals using an intelligent multiplexer, and transmitting the aggregated signal to a signal acquisition circuit for processing. The method also includes holding signals at the respective cells, time-aligning the signals before aggregation, and injecting a snapshot signal to control the timing of signal sampling at the cells. Overall, the patent highlights a sophisticated system for efficiently sensing and processing brain signals, potentially opening up new possibilities in the field of neuroscience research and medical applications.
