Millions of Americans now head out the door each day wearing devices that count their steps, check their heart rates, and help them stay fit in general. But with further research, these “wearables” could also play an important role in the early detection of serious medical conditions. In partnership with health-care professionals, people may well use the next generation of wearables to monitor vital signs, blood oxygen levels, and a wide variety of other measures of personal health, allowing them to see in real time when something isn’t normal and, if unusual enough, to have it checked out right away.
In the latest issue of the journal PLoS Biology , an NIH-supported study offers an exciting glimpse of this future. Wearing a commercially available smartwatch over many months, more than 40 adults produced a continuous daily stream of accurate personal health data that researchers could access and monitor. When combined with standard laboratory blood tests, these data—totaling more than 250,000 bodily measurements a day per person—can detect early infections through changes in heart rate.

Whether it’s a pedometer dangling from a belt loop or a skin patch to monitor heart rate and hydration levels, wearable and mobile devices have become essential gear for many of today’s fitness minded. But Darren Lipomi, a nanoengineer at the University of California, San Diego, envisions even more impressive things to come for optimizing workouts and bringing greater precision to health care. Lipomi is helping to build a future of “stretchable electronics,” semiconducting devices that will more seamlessly integrate with the contours of our bodies, outside and even inside, to monitor vital signs, muscle activity, metabolic changes, and organ function—to name just a few possibilities.
Lipomi and his colleagues specifically want to create a new class of semiconducting polymer that has the mechanical properties of human skin. This transparent “electronic skin” will have a soft elasticity to conform to shape, sense contact, absorb blunt force, and even self heal when dinged. It will do all of this—and possibly more—while continuously and wirelessly performing its programmed health-monitoring function. To help Lipomi build this future of real-time health monitoring, he has been awarded a 2015 NIH Director’s New Innovator Award. This NIH award supports exceptionally creative new investigators who propose highly innovative projects with the potential for unusually high impact.

After college, Perry Hystad took a trip to India and, while touring several large cities, noticed the vast clouds of exhaust from vehicles, smoke from factories, and soot from biomass-burning cook stoves. As he watched the rapid urban expansion all around him, Hystad remembers thinking: What effect does breathing such pollution day in and day out have upon these people’s health?
This question stuck with Hystad, and he soon developed a profound interest in environmental health. In 2013, Hystad completed his Ph.D. in his native Canada, studying the environmental risk factors for lung cancer [1, 2, 3]. Now, with the support of an NIH Director’s Early Independence Award, Hystad has launched his own lab at Oregon State University, Corvallis, to investigate further the health impacts of air pollution, which one recent analysis indicates may contribute to as many as several million deaths worldwide each year .
