Your body alerts you to many aspects of your health. Your stomach growling tells you when to eat. A powerful yawn lets you know you’re tired. Your body gives off many other valuable signals, but requires technology to detect them. Scientists are looking for new ways to track and use your body’s signals to improve your health and manage disease.
Physical activity trackers and step counters are now helping people develop and maintain healthy habits. These devices have also opened doors for people to participate in health research. Now, researchers are designing more advanced devices called biosensors that measure biological, chemical, and physical signs of health.
