Abstract
An arm-wearable device for sensing neuromuscular signals using a shared reference electrode that is shared between two or more electrodes is provided. The arm-wearable device includes a structure configured to be worn by a user, the structure having an interior surface configured to contact a user's skin when the arm-wearable device is donned by the user. The arm-wearable device includes a first electrode, a second electrode, and a shared reference electrode, each electrode contacts the user's skin above respective neuromuscular pathways of the user when the wearable structure is worn by the user. The first and second electrodes detect neuromuscular signals and the shared reference electrode detects a reference neuromuscular signal. The arm-wearable device includes circuitry configured to compare the neuromuscular signals and the reference neuromuscular signal to determine a motor action that the user intends to perform with their hand.
