Digital biomarkers can help gather rich data about patients, passively and remotely. It would be tough to collect enough data for drug approval based on such sparse measures. Let’s say a clinical trial collects blood sugar readings from patients who visit the clinic every month. Four reasons why digital biomarkers are game-changers “Today, we have many such digital biomarkers emerging for research and clinical use, such as keystroke dynamics, voice, eye tracking, facial recognition, smell, and gait,” says Richie Bavasso, Co-Founder and CEO of nQ Medical. ![]() For example, voice signals from a smartphone’s microphone can detect mild cognitive impairment due to Alzheimer’s disease. Additionally, scientific evidence needs to show that the health attribute measured by the device maps consistently and accurately to a clinical outcome. The measures must be objective, quantifiable, and reproducible. When can such novel health measures function as medical biomarkers? Fitbit trackers use sensors such as accelerometers to tell how many steps we’ve taken in a day or how fast we’ve been walking. Modern digital devices measure several health parameters. Common examples include blood pressure readings, heart rate, and even genetic test results. What are biomarkers? They are medical signals that can measure health in an accurate and reproducible way. Smart devices and wearables are all around us getty
