在臺灣地區由於地理位置、地形等因素，季風通常挾帶豐沛的水氣造成空氣當中含水量極高，特別是在夏季時刻經常形成溼熱氣候，此時便提供了細菌與黴菌滋生良好的環境條件。溼熱氣候不僅造成人類皮膚的黏膩與不適感之外，嚴重者可能造成皮膚過敏與相關病變而必須接受醫療處置。但是傳統的皮膚病變其醫療處置方法均伴隨著許多的副作用，使得醫師在進行診斷以及決策醫療處置的方法時必須審慎考慮治療患部之後所帶來的副作用影響，同時治療成效受到患者體質影響效果不一。
近年來受惠於美容醫學產業的興盛發達，多項針對皮膚病變醫療處置的方法其研究報告指出：紅外線（不可見光）對於皮膚患部因黴菌滋生所造成的病變具有顯著的治療成果，同時紅外線對於皮膚患部的治療不會造成任何的副作用以及不良影響，該治療方法其原理稱為：光導去活化 (Photoinactivation)。
於是本研究擬將光導去活化的原理應用在日常生活的物品以及建築空間當中，透過實際製作紅外線光源產生裝置，調整與最佳化光源照射的各項物理參數，接著進行光導去活化對於細菌與黴菌抑制與減緩的實驗（細菌培養實驗），驗證光導去活化在日常生活以及建築空間應用的可能與可行性，以提昇臺灣地區的居住品質與生活環境，改善個人的衛生條件。配合紅外線光源產生裝置製作的工作，本研究也將導入產品外形、仿生設計、綠能科技、硬體裝置製作與建築空間結合等議題，進行一連串的設計研發、規劃製作以及實驗測試等工作。
將光導去活化予以生活化便是本研究的重要目標，透過製作出不同的紅外線光源產生裝置型態的原型，進行實驗以及交叉驗證，配合不同的建築空間以及使用情境設定，例如：建築物的空調設備、特定用途與環境如住宅、食品、醫療以及校園環境、淨水處理等不同的環境條件要求，研究光導去活化在以上情境與環境設定上應用的可行性，本研究確實將美容醫學的研究具體化在建築與生活空間當中。

The island of Taiwan is surrounded with oceans, and the monsoon always brought Taiwan a humid climate. Therefore the humid climate may bring about the fertile grounds for bacteria and fungi, the bacteria and fungi may make a bad condition of our living environment. Who is long-term livelihood in a bad living environment, especially the bacteria and fungi may make a hypersensitivity disorder. But the traditional therapy sometimes bring about the different side effects, therefore this practice is aim at try to find out the other way to solve this problem.
According to the results of experiment of the near-infrared light, it is able to damage the bacteria and fungi, which is called the effect of photo-inactivation. The near-infrared light will not bring about any side effects. Therefore the photo-inactivation may replace the traditional therapy recently.
This practice is the interdisciplinary cooperation. In the first stage of practice is to analyze the related products on the market, the problem of related products is the source of ultraviolet can cause the skin cancer. Therefore in the second stage is to practice the hardware of electric circuits. And the entire set of hardware, including the infrared light-emitting diode module, rechargeable battery and photovoltaic cell. In the third stage is the experiment for photo-inactivation, and the photo-inactivation was confirmed by further experiments. In the last stage is the design of appearance of the product, such as the function of operation, the assembly of element, quality check, and the positioning of marketing.
The most important is to achieve the consequence of the photo-inactivation in this practice. The kernel of this practice is the near-infrared light-emitting diode, and we concluded that the new device was able to keeping in sanitation of the living environment as the further experiments. Therefore we inferred from this practice that the application of photo-inactivation to other case, which is require keeping in sanitation.
