Adjusting an operational characteristic of one or more neuromuscular-signal sensors to maintain desired impedances, and systems, wearable devices, and methods of use thereof

A wrist-wearable device including one or more neuromuscular-signal sensors, the wrist-wearable device configured to perform or cause the performance of:

• monitoring, based on data from a wearable device that includes a neuromuscular-signal sensor, an impedance at the sensor that impacts the neuromuscular-signal sensor's ability to sense neuromuscular signals, wherein the neuromuscular-signal sensor is:
• coupled to the wearable device such that it contacts a portion of a user's skin when the wearable device is donned by the user, and
• depressed into the user's skin a first skin-depression depth when the wearable device is donned by the user;
• and
• in response to detecting a change in the impedance at the neuromuscular-signal sensor that causes the impedance to be outside of a predefined range of impedance values:
• causing an adjustment to an operational characteristic associated with the neuromuscular-signal sensor so that the impedance at the neuromuscular-signal sensor is within the predefined range of impedance values after the adjustment to the operational characteristic of the neuromuscular-signal sensor,
• wherein the causing the adjustment to the operational characteristic associated with the neuromuscular-signal sensor includes causing a depression of the neuromuscular-signal sensor to change such that the neuromuscular-signal sensor is depressed into the user's skin a second skin-depression depth that is distinct from the first skin-depression depth.

A non-transitory computer-readable storage medium including instructions that, when executed by one or more processors of a wrist-wearable device that includes one or more neuromuscular-signals, cause the wrist-wearable device to perform or cause the performance of:

• monitoring, based on data from a wearable device that includes a neuromuscular-signal sensor, an impedance at the sensor that impacts the neuromuscular-signal sensor's ability to sense neuromuscular signals, wherein the neuromuscular-signal sensor is:
• coupled to the wearable device such that it contacts a portion of a user's skin when the wearable device is donned by the user, and
• depressed into the user's skin a first skin-depression depth when the wearable device is donned by the user;
• and
• in response to detecting a change in the impedance at the neuromuscular-signal sensor that causes the impedance to be outside of a predefined range of impedance values:
• causing an adjustment to an operational characteristic associated with the neuromuscular-signal sensor so that the impedance at the neuromuscular-signal sensor is within the predefined range of impedance values after the adjustment to the operational characteristic of the neuromuscular-signal sensor,
• wherein the causing the adjustment to the operational characteristic associated with the neuromuscular-signal sensor includes causing a depression of the neuromuscular-signal sensor to change such that the neuromuscular-signal sensor is depressed into the user's skin a second skin-depression depth that is distinct from the first skin-depression depth.
