一个可伸缩的OLED的新路线
在洛杉矶的加利福尼亚大学的研究人员已经证明,它有可能使内在的可拉伸的有机发光二极管(OLED)使用碳或更多导电银纳米管,可能创造出新的LED的应用及市场机会。
“可拉伸电子正从一个概念的好奇心为现代电子产品的一个重要分支。这种设备可以用于广泛的应用,包括可穿戴式电子产品可能是有用的,“智能皮肤,微创生物医学设备,”加州大学洛杉矶分校的研究人员,支斌宇,萧帆牛,支天柳,齐冰佩。
具体而言,制造商们已经开始探索如何伸缩性或弹性的电子可以克服现行的医疗设备共同的挑战,如慢性伤口的管理,这是在全球范围内,婴儿的呼吸监测的一个主要的健康问题,通常更难,因为胸部和腹部膨胀正常呼吸。在更大的范围内,弹性LED可以用来包装广告牌、建筑物、公共汽车或类似的结构和车辆。
The previous approach
Various researchers and manufacturers have already had some success realizing the benefits of stretchable or elastic electronics, including devices with LEDs. But the current approach is significantly different from how the UCLA researchers approached the problem. Presently, it is common to find rigid LEDs embedded or otherwise bound to a soft rubbery polymer so that the polymer provides the elasticity while the active electronics are not actually deformed.
With this approach the most difficult challenge can be the interconnections that must be able to expand and contract with the rubbery polymer. What is different about the UCLA approach is that it seeks to make the entire LED pliable, including the anode, cathode, and interconnects.
