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.
