| Summary: | 碩士 === 國立虎尾科技大學 === 光電工程系光電與材料科技碩士班 === 105 === Due to the global warming and the ozone layer depletion year after year, Ultraviolet (UV) light is easily passing through the ozone layer, causing substantial harm to human beings. On the other hand, appropriate exposure to ultraviolet is also beneficial to bone health, producing vitamin D3 as well as being transformed by human body into t vitamin D3.
In recent years, smart phones are so popular, becoming the current necessity of daily life; wearable devices combined with smart phones have become the current trend. In this paper, we mounted a UVB (280-320nm) optical sensor on a watch, associating both blue tooth and cell phone’s app to accomplish the goal of remote connection/access; the proposed system can record both the accumulation of exposure to sunlight, producing a certain amount of vitamin D3IU, and the UV level. Finally, users can realize how much is lacking for a daily doze of Vitamin D3.
