在這環保及性能並重的時代，有機光電感測器的發展日益蓬勃。生物高分子材料-吉利丁具有良好的機械性質且可低溫溶液式製程，因此已廣泛用於有機記憶電子元件領域。但吉利丁於光感測元件的應用，因受限於吉利丁膜對光無感測能力，因此較少研究探討。
因此本研究透過金屬鹽類-硝酸銀的添加，提高吉利丁光感測元件對光的響應。另外，亦透過絲線射出技術，製作出吉利丁/銀複合奈米絲線，由於絲線結構，感應膜層體表面積急劇擴大，可提高光在材料內的機率，進一步提升光感測元件的性能。除此之外，為了提升吉利丁/銀複合奈米絲線的線徑可控制性和分布均勻性，本研究亦將原本棉花糖機設備重新改造設計，透過改良後的絲線射出設備製作線徑為400奈米的吉利丁/銀複合奈米絲線，並有效地提升光感測性能，為吉利丁於有機光電元件的發展提供多一種可能。

In this era of environmental protection and performance, the development of organic photoelectric sensors is advancing. The biopolymer material gelatin has good mechanical properties and can be processed in low-temperature solutions, and thus, it has been widely used in the field of organic memory electronic devices. However, the application of gelatin in light-sensing components is limited by the gelatin film’s incapability to sense light, resulting in limited research and discussion.
Therefore, in this study, whether the addition of metal salt–silver nitrate can improve the response of the gelatin photo-sensing element to light was investigated. In addition, the gelatin/silver composite nanowire was produced through thread injection technology. Given the thread structure, the surface area of the sensing film layer was greatly expanded, which can increase the probability of light in the material and further improve the performance of the light-sensing element. In addition, to improve the wire diameter controllability and distribution uniformity of the gelatin/silver composite nanowire, we redesigned the original cotton candy machine equipment and determined the wire diameter through the improved wire injection equipment. The 400 nm gelatin/silver composite nanowire can effectively improve the light-sensing performance, providing another possibility for the development of gelatin in organic optoelectronic devices.
