Wearable technology has been a hot topic in medical innovation for several years now. A growing number of people choose to track their own physical condition using FitBits, Jawbones and other activity trackers, tiny wearable devices that monitor your movements, pulse rate, sleep patterns and more. Once the preserve of obsessive fitness fanatics, “self-monitoring” has the scope to transform healthcare. The ever-increasing number of people with chronic conditions can track and electronically report their symptoms, reducing the number of routine (and expensive) consultations they need with medical staff and ensuring a quicker response to changes that do require direct professional attention.
