Quell is a soon-to-be available wearable device that sends electric pulses through skin to counter pain

Quell, a wearable first introduced at CES 2015, has gained a 501(k) approval from the FDA which allows distribution and purchase without the need for prescriptions. The Quell system is the younger brother of Sensus, a prescription-needed anti-pain wearable from the same company NeuroMetrix.

Both the Quell and Sensus use the same technology but at different degrees to provide users relief from pain. Using a method called TENS or transcutaneous electrical nerve stimulation, both devices provides non-invasive pain relief. Electrodes applied to skin will send pulses through nerves that will reach the brain to release pain blockers in the spine.
