A connector may include a first housing configured to detachably secure a first input cable of a first sensor configured to generate a first signal, and a second housing configured to detachably secure a second input cable of a second sensor configured to generate a second signal. The second housing may be configured to transmit the second signal from the second input cable to the first housing. The first housing may be configured to transmit at least one of the first signal and the second signal to an output cable. A coupling of the first housing may be configured to mate with a coupling of the second housing such that the first housing and the second housing are configured to be detachably secured to each other. The coupling may be mechanical, electro-mechanical, or magnetic. Either sensor may be an electrocardiogram sensor or a pulse oximetry sensor.

A device for functional electrical stimulation (FES), neuromuscular electrical stimulation (NMES), and/or in receiving electromyography (EMG) signals includes a sleeve and electrodes. The sleeve is sized and shaped to be worn on a human arm, and comprises a stretchable fabric The sleeve has a distal end disposed on or adjacent a wrist of the human arm when the sleeve is worn on the human arm and a proximal end opposite from the distal end. The electrodes are secured with the sleeve and positioned to contact skin of the human arm when the sleeve is worn on the human arm. The sleeve may include an inner sleeve contact with the skin and an outer sleeve disposed over the inner sleeve. The inner sleeve has openings in which the electrodes are disposed.
