Abstract: An example band structure is provided which includes a first portion having an embedded structural member for holding one or more signal-processing components in fixed positions within the first portion of the band structure. The first portion also includes the one or more signal-processing components, which are coupled to the embedded structural member, and the one or more signal-processing components are configured to at least partially process neuromuscular signals. And the first portion includes one or more neuromuscular-signal-sensing electrodes attached to the first portion of the band structure and electrically coupled to the one or more signal-processing components. The band structure also includes a second portion that does not include any electrical components, where the first portion of the band structure and the second portion of the band structure are each configured to couple directly to one another to form a loop sized to accommodate a wrist of a user.
