Supported by the NIH Genes, Environment and Health Initiative, Dr. Sun and his colleagues have developed a unique electronic device called the eButton for objective measurement of lifestyle (including diet, physical activity, environment, social interaction, etc.), diagnosis of certain behavior-related neurological disorders, and assessment of therapeutic effects.
This “all-in-one” device appears as a chest button (62mm in diameter, 10mm in thickness) with a personalized design. It can be conveniently attached to a jacket or a shirt using a pin or a pair of magnets. eButton contains a low-power, high-performance microprocessor. The mass storage of this device is a micro SD card with enough capacity to hold more than one week of data. eButton is also equipped with a variety of electronic sensors including a video camera, a GPS sensor, a multi-axis accelerometer, a multi-axis gyroscope, a daylight sensor, and a thermometer.After a designated study period on patients, the device is returned to the lab where the stored data are uploaded to a computer for analysis.
Dr. Sun and his colleagues have conducted a series of laboratory tests and evaluated this device on 18 human subjects for more than 1000 hours in real-life settings. This work has been well-received by the research community, highlighted by Nature magazine, and reported in public media worldwide.
