The global market for pain management wearable medical devices is set to double by 2022, a new report from The Business Research Company, Wearable Medical Devices Global Opportunities and Strategies To 2022, shows. Wearable medical devices are small electronic products, often consisting of one or more sensors, that have computational capability. They are embedded into items that are attached to body parts, such as the head, feet, arms, wrists and waist. They can resemble a watch, eyeglasses, clothing, contact lenses, shoes or even jewellery. Straps are currently the most popular way of wearing a medical device, and this segment of the market is growing rapidly, but so are two other segments, headbands and shoe sensors, while handheld and other methods are also growing, but a little less fast.
