As expected, wearables are all the rage at CES 2015. And while most of them are about looking fancy and sending useful notifications to your wrist, there are also others whose goal is to keep you feeling healthy. Enter NeuroMetrix Inc’s Quell, a wearable that attaches to your upper calf and promises to make chronic pains go away within 15 minutes of putting it on. Quell’s OptiTherapy electrode-driven technology uses non-invasive nerve stimulation to make this possible, allowing it to provide “100 per cent” prescription-free relief to anyone who uses it. The company behind it, NeuroMetrix Inc, says that Quell is capable of relieving different types of chronic aches, from nerve pain to lower back problems.
Here’s how it works: Quell stimulates the sensory nerves in your calf, then sends neural pulses to your brain, where they trigger the body’s natural pain relief response releasing endogenous opioids. Finally, these opioids send pain signals toward the delta opioid receptor, which is what triggers those tedious feelings, and reduces the amount of pain you are experiencing. On a single charge, Quell is able to provide up to 40 hours of relief, while Bluetooth connectivity allows it to pair with an iOS device and to track your therapy as well as sleep quality.
It will be available later this spring for $250(£160) — and it has FDA approval already, something that is always a good sign for any medical gizmo.
