Among the different varieties of wearables like watches trackers and

sensors of CES, the one that stood out was called Quell, a drug-free

device supposed to help out relieve chronic pain.

The device apparently works by stimulating sensory nerves once placed

on the upper calf, which then carry neural pulses to the brain,

triggering a natural response that is supposed to block pain and

improve sleep.
