According to Verily’s official blog, the Study Watch was designed using feedback from users, researchers and clinicians to ensure it had high quality sensors and was user friendly enough to ensure continuous usage.
The Study Watch includes multiple physiological and environmental sensors designed to measure relevant signals for studies such as cardiovascular and movement disorders, including ECG, heart rate, electrodermal activity and inertial movements.
For easy use in clinical studies the Study Watch has a battery life of one week as well as adequate internal storage and data compression so the wearable can store a weeks’ worth of raw data, eliminating the need to frequently sync it.
According to Verily, the Study Watch also boasts a powerful processor that supports real-time algorithms on the device and has firmware designed to be robust for future extensions, such as over-the-air updates, new algorithms and user interface upgrades.
The Study Watch’s user interface consists of a low power, high resolution always on screen which displays the time as well as certain instructions specific to the trial.
“Because the investigational device stores health data, all data are encrypted on the device for security. The encrypted data are uploaded and processed in the cloud using Verily’s backend algorithms and machine learning tools. This infrastructure is highly scalable and can serve population studies consisting of large volumes of data,” said the official blog.
The Study Watch is not for sale, but will rather be used in several observational studies conducted by Verily’s partners, including the Personalized Parkinson’s Project, a multi-year study to identify patterns in the progression of Parkinson’s disease with the aim of developing more personalised treatments; and another study that will explore the transitions between health and disease.
Future plans include incorporating the Study Watch in a broad array of health applications.
