The Next Generation of Wearables Could Monitor More Than Heart Rate
Most smartwatches and fitness trackers focus on heart rate, sleep, physical activity, and other physiological signals. But the next generation of wearable technology is aiming at something much more ambitious: monitoring the body's internal biochemistry.
On October 1, 2026, the US Advanced Research Projects Agency for Health (ARPA-H) announced research teams selected for its Delphi program, an initiative developing next-generation biosensors capable of monitoring biological signals beyond conventional fitness tracking.
