Urban microclimates generate localized heat and radiation spikes, while standard static textiles cannot dynamically alter their exposure to radiant energy. In nature, heliotropic plants like sunflowers (Helianthus annuus) continuously adjust cellular structures in response to ambient light to optimize light absorption and thermal balance.
城市微氣候經常導致極端的區域性高溫與輻射。傳統靜態布料無法動態調節太陽輻射暴露。仿生學提供了另一種思維：向日葵（Helianthus annuus）能根據光照強度動態調整結構，在獲取能量與散熱之間取得平衡。
Prototype an autonomous, heliotropic "second skin" using a photoresistor (LDR) and an SG90 micro-servo motor. When exposed to peak ambient irradiance (sunlight/flashlight), the garment mechanically deploys kinetic paper louvers to shade the body and promote airflow (Red LED ON, Servo sweeps to $90^\circ$–$110^\circ$); in shaded environments, it returns flush to preserve thermal comfort (Green LED ON, Servo at $10^\circ$).
設計並製作一款仿生「第二層肌膚」穿戴式局部機構，整合微型伺服馬達與光敏電阻（LDR）。系統感應到強光照度時，自動驅動布料或紙百葉機構張開遮陽防護（紅燈亮起，馬達轉至 $90^\circ$–$110^\circ$）；於陰影或低光環境下自動收合平貼（綠燈亮起，馬達歸位至 $10^\circ$）。
Ensure all connections are verified on the breadboard prior to connecting the 5V power supply.
請於通電（5V）前完成麵包板上的電路對接與線路複查。
