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.

灵活，可拉伸和透明的电子材料在无数新颖的应用中发挥着核心作用，这些应用在我们的社会中会变得无处不在，例如人造肌肉和皮肤，智能纺织品，生物医学设备，假肢和灵活的展示。这些新领域的电子产品的进展是在数十年来的材料科学的激烈研究和开发之后，这导致了材料结合了通常相互排斥的材料。例如，现在表现出高机械合规性，电导率和透明度的材料现在已成为现实。 如今，人们对两类材料进行了极大的关注，这些材料对柔性，可拉伸和透明的电子设备非常有吸引力：有机导电聚合物和金属氧化物半导体。两种类型的材料都有机会使用低成本的基于溶液的技术对各种底物沉积透明膜。广泛的设备采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。 尽管取得了这种进步，但我们仍面临许多挑战，然后才能充分利用这些材料的潜力来获得柔性，可拉伸和透明的电子产品。进行聚合物的一种特别理想的特性，尤其是用于生物电子药物的应用，是自我修复损害的能力。例如，这将允许植入能够在恶劣的机械条件下工作的设备而无需频繁更换。另一个具有挑战性的问题是，能够对具有高空间分辨率在非常规底物（例如弹性体）上进行高空间分辨率进行模拟。对于金属氧化物，尽管已经在展示行业中使用了镀锌锌（Igzo），但有必要找到比IN和GA更丰富的元素，可以使用低成本，基于溶液的技术处理。 该发现研究计划的目的是：开发用于自我修复的电子材料，柔性/可拉伸电子设备和金属氧化物电子产品的破坏性技术，并应用了可穿戴的电子设备，生物电子和透明电子产品，并提供对这些材料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，设备制造以及对材料基本特性的高级探索。 由于其多学科的特征，即生产高影响力的科学和创新技术的潜力，该研究计划代表了培训高素质人员的非凡机会，以应对我们社会的科学和技术挑战。
