A system, device, and method for transcutaneous nerve stimulation such as facial nerve stimulation, and in particular, to using transcutaneous nerve stimulation for artificially eliciting eye blink, such as with humans with acute facial paralysis (Bell's palsy or Dry Eye syndrome), is disclosed. A battery-operated wearable device may employ a pulse generator for periodically and automatically generating bursts train of asymmetrical Bi-Phasic square pulses. The output pulses are fed to two electrodes that are attached to the skin of the treated person to stimulate the facial nerve for eliciting blinking at a rate that mimics normal blinking operation. The device may include a sensor and a wireless connection, and the parameters of, or the activation of, the generated bursts may be controlled by the sensor output, by human user control, or by data received from the wireless network. Further, the device may transmit status to the wireless network.

Methods and systems for treating sleep apnea using electrical stimulation to a patient's upper and/or lower respiratory nerve or muscle are described. A stimulation regimen can be used to achieve upper airway patency and/or rhythmic air flow in a coordinated fashion during sleep. In some cases, diaphragm activity is monitored to determine whether sufficient upper airway patency and/or rhythmic air flow is achieved and maintained. The stimulation regimen may be adjusted based on the diaphragm activity. In some cases, the system includes modularized components so that the components can be customized to an individual's needs.
