Verily Life Sciences LLC, a subsidiary of Google’s parent company Alphabet, announced on Wednesday the initiation of the Project Baseline study, which will collect broad phenotypic health data from approximately 10,000 participants across at least four years.

Data collection will include the use of a sensor that will be placed under the bed mattress of participants to passively monitor their sleep habits. Data will be compiled into a digital platform (like Google Maps for health), and tools will be developed so that qualified researchers can search and analyze data within the platform.
