1) Wearable eButton for Evaluation of Energy Balance with Environmental Context and Behavior
In this study, Dr. Sun proposes the refinement of eButton, an electronic device that was developed under the NIH GEI diet and physical activity research program. This button-like device can be attached to clothing and worn on the chest using a pair of magnets or a pin. The new eButton will contain numerous innovative designs, including a motion sensor to detect physical activity, an optical eating detector to monitor eating/drinking/smoking, two miniature cameras that produce a stereo vision to measure food portion size without depending on a reference card. The eButton will store the multimedia data acquired by these advanced miniature sensors in a flash memory within the device. It will also have a wireless link to a smart phone which will allow researchers to monitor the operating status of eButton and communicate with subjects remotely in real time. During the first year of this research, the new eButton and associated algorithms/software is being designed and constructed in Dr. Sun’s laboratory by an experienced team of electronic/software engineers based on its early version developed under the NIH GEI diet and physical activity research program. Once eButton is constructed, Dr. Sun will implement a thorough validation process using human subjects to evaluate its accuracy in diet and physical activity assessment.
2) Biomimetic Self-Adhesive Dry EEG Electrodes
This biomedical engineering project aims to develop a novel skin-surface electroencephalogram (EEG) electrode. This new electrode does not require application of electrolyte; is able to penetrate scalp hair easily during electrode placement; can be quickly applied and removed; has low and stable electrode impedance; and has an extraordinary ability to self-adhere to the scalp without glue or tape. Its unconventional design is inspired from a biological system (the toe of geckos) which has shown clear effectiveness in the natural environment. In the current stage, design and construction of the electrode is being conducted and a test bed is being constructed to evaluate its performance.
