Not every wearable is about sleep tracking or counting steps. Among the many wearables showed at CES 2015, a useful one was called Quell. It is a drug-free service that helps in relieving chronic pain. The technology used for this device has been developed by Neurometrix, a company from Harvard Medical School which specialises in Neurotechnology.
This device consists of a strap that is worn around the affected part of the body, with its electrode touching the skin. When activated, it stimulates the nerves, in turn sending a message to the brain to release endogenous opioids- the body’s natural defence against pain. This brings relief within 15 minutes.
The main advantage of this device is that it is portable and can be carried along almost anywhere. The correct stimulation has to be attuned the first time, and Quell then automatically selects the same each time. iOS already has a supporting app and Android one is on its way.
The only shortcoming would be the user will have to keep on buying the electrodes periodically. Normally, this would cost $250 (approx Rs. 15,773), but pre-ordering would cost $199 (Rs. 12,555). Details about its mass availability is still uncertain, though the device is currently up for pre-order on Indiegogo. The device has already reached $250,000 in pledges.
