Electronic phenotyping is a research area that involves using electronic health records, wearable sensors, and other digital tools to gather and analyze data on an individual's health and behaviors. This data can be used to track and monitor changes in a person's health, identify patterns that may indicate the presence of a particular condition or disease, and inform decisions about treatment and care. Electronic phenotyping has the potential to revolutionize healthcare by enabling personalized, data-driven approaches to diagnosis, treatment, and prevention.
