The innovations I describe here—many of which are still in early stages—are impressive in their own right. But I also appreciate them for enabling the shift away from our traditional compartmentalized health care toward a model of “connected health.” We have the opportunity now to connect the dots—to move beyond institutions delivering episodic and reactive care, primarily after disease has developed, into an era of continuous and proactive care designed to get ahead of disease. Think of it: ever present, analytics-enabled, real-time, individualized attention to our health and well-being. Not just to treat disease, but increasingly, to prevent it.
Just a decade after the first Fitbit launched the “wearables” revolution, health tracking devices are ubiquitous. Most are used to measure and document fitness activities. In the future these sensing technologies will be central to disease prevention, diagnosis, and therapy. They’ll measure health objectively, detect changes that may indicate a developing condition, and relay patients’ data to their clinicians. Flexible, electronic medical tattoos and stick-on sensors can take an electrocardiogram, measure respiratory rate, check blood sugar, and transmit results seamlessly via Bluetooth. It’s mobile vital sign tracking, but at a level once found only in an intensive care unit. Hearing aids or earbuds with embedded sensors will not only amplify sound but also track heart rate and movement. Such smart earpieces also could be integrated with a digital coach to cheer on a runner, or a guide to lend assistance to dementia patients. Smart contact lenses in the future will be packed with thousands of biosensors, and engineered to pick up early indicators of cancer and other conditions. Lenses now in development may someday measure blood sugar values in tears, to help diabetics manage diet and medications.
