Flexible, stretchable and transparent electronic materials are playing a central role in a myriad of novel applications that are expected to become ubiquitous in our society, such as artificial muscles and skin, smart textiles, biomedical devices, prosthetics and flexible displays. Progress in electronics for these new fields comes after decades of intense research and development in materials science, which have resulted in materials combining properties that are often mutually exclusive. For instance, materials showing high mechanical compliance, conductivity and transparency are now a reality. Enormous attention is being paid nowadays to two classes of materials that are very attractive for flexible, stretchable and transparent electronics: organic conducting polymers and metal oxide semiconductors. Both types of materials offer the opportunity to deposit transparent films using low-cost, solution-based techniques on a variety of substrates. A wide range of devices employ conducting polymers and semiconducting metal oxides as the electroactive materials. These include transistors, light-emitting diodes, biomedical devices, and chemical and mechanical sensors. In spite of this progress, we face many challenges before we can fully exploit the potential of these materials for flexible, stretchable and transparent electronics. A particularly desirable property for conducting polymers, especially for applications in bioelectronics, would be the ability to self-repair damage. This would permit, for instance, implanted devices capable to work under harsh mechanical conditions without need for frequent replacement. Another challenging issue is the ability to pattern conducting polymer devices with high spatial resolution on unconventional substrates, such as elastomers. For metal oxides, although gallium indium zinc oxide (IGZO) is already used in the display industry, there is a need to find elements more abundant than In and Ga, which can be processed with low-cost, solution-based techniques. The objective of this Discovery Research Program is: developing disruptive technologies for self-healing electronic materials, flexible/stretchable electronic devices and metal oxide electronics, with applications in wearable electronics, bioelectronics and transparent electronics, and providing a fundamental understanding of the phenomena controlling the electrical and mechanical properties of these materials and devices. Our work will include materials processing and patterning, device fabrication and advanced exploration of fundamental properties of materials. Because of its multidisciplinary character, its potential to produce high-impact science and innovative technology, this Research Program represents an exceptional opportunity to train highly qualified personnel, to respond to the scientific and technological challenges of our society.

柔性、可伸展和透明的电子材料在无数新的应用中发挥着核心作用，这些应用预计将在我们的社会中变得无处不在，如人造肌肉和皮肤、智能纺织品、生物医疗设备、假肢和柔性显示器。这些新领域的电子学进展是在材料科学数十年的紧张研究和发展之后取得的，这些研究和发展导致了材料结合性能往往是相互排斥的。例如，具有高机械柔顺性、导电性和透明度的材料现在已经成为现实。目前，对柔性、可伸缩和透明电子设备非常有吸引力的两类材料正受到极大的关注：有机导电聚合物和金属氧化物半导体。这两种材料都提供了在各种衬底上使用低成本、基于溶液的技术沉积透明薄膜的机会。许多器件使用导电聚合物和半导体金属氧化物作为电活性材料。这些包括晶体管、发光二极管、生物医学设备以及化学和机械传感器。尽管取得了这些进展，但在我们能够充分开发这些材料用于柔性、可拉伸和透明电子产品的潜力之前，我们面临着许多挑战。对于导电聚合物，特别是在生物电子学中的应用，一个特别令人满意的性质是能够自我修复损伤。例如，这将允许植入的设备能够在苛刻的机械条件下工作，而不需要频繁更换。另一个具有挑战性的问题是在弹性体等非传统衬底上形成具有高空间分辨率的导电聚合物器件的能力。对于金属氧化物，尽管镓铟锌氧化物(IGZO)已经在显示行业中使用，但需要找到比In和Ga更丰富的元素，这些元素可以用低成本的基于溶液的技术进行处理。该发现研究计划的目标是：开发自我修复电子材料、柔性/可拉伸电子设备和金属氧化物电子设备的颠覆性技术，并在可穿戴电子设备、生物电子和透明电子设备中应用，并提供对控制这些材料和设备的电气和机械性能的现象的基本了解。我们的工作将包括材料加工和图案化、器件制造和对材料基本性质的高级探索。由于其多学科的特点，其产生高影响力的科学和创新技术的潜力，这一研究计划代表着一个培养高素质人才、应对我们社会的科学和技术挑战的绝佳机会。
