University of California, San Diego, La Jolla, CA MaXentric Technologies, La Jolla, CA 1 2 Wearable ExG biopotential acquisition systems can potentially capture a wealth of clinically useful diagnostic information during activities of daily life. In practice, however, motions from common activities introduce large artifacts that can easily saturate traditional analog front-ends (AFEs) designed to sense biopotentials on the micro- to milli-volt scale. In addition, the wires that connect each electrode to an array of high-impedance AFEs can easily pick up interference and large, potentially saturating artifacts. For these reasons, many-channel monolithic biopotential sensing systems are often fragile and difficult to use in ambulatory environments. While active electrodes can be used to combat interference picked up by high-impedance wires, they require power-hungry drivers to deliver highfidelity signals across relevant anatomy to an array of ADCs.
