US Patent 11751789 Wearable device with conductive traces and insulator

The present disclosure relates to a wearable device that includes a housing, battery terminal connector, conductive traces, and an insulator for recording signals. The device may include a housing enclosing a circuit board and a battery. The device may include two conductive traces electrically connected to terminals of the battery and an insulator separating the conductive traces. The battery terminal connector can present both the conductive traces to the outer surface for coupling to a circuit board. The device can assess the physiological signals to infer a likelihood of arrhythmia of a user.
