Abstract
The demand for measurements of fatigue and mental stress in our life, which leads to low tragic accidents, low efficacy, and illness is now becoming bigger in recent years. In order to solve these problems, we fabricated a micro-fabricated eyeglass-shape optical sensors system in our prior work. The fabricated sensors system can detect subject’s blinks by its dye-sensitized photoelectric cells or DSSCs. However, the DSSCs have possibilities to obstruct subject’s line of sight because of its position. The DSSCs are arranged on the center of glass substrate. In this study, we considered optimal placement of DSSCs to detect subject’s blinks without disturbances. It was experimentally revealed that detection sensitivity of blinks depends on the distance between DSSCs and subject’s pupil. We conclude that DSSC should be placed on where it does not disturb user’s visual field and close to user’s eyeball.
