Google Science Fair

In the google science fair, I think the "wearable sensors" for tracking the movements and wanderings of Alzheimer's patients by Kenneth Shinozuka is the most efficient and one that would effect our society the most for three reasons. The first is that is is easy and cheap to create, as it does not use many materials for the sensors. Another important reason is that it would save a lot of Alzheimer's patients from wandering off and getting into an accident at night. Finally, I think that one last reason this should be voted as the best "Google Science Project" is that the the sensor is lightweight and easy to use, and finally that it will relieve a lot of stress for the caretakers of people with Alzheimer's.
