兼容和可生物降解的电子材料是人类和生态良性技术的核心，包括医疗植入物、食品监测、可穿戴电子产品、可现场环境传感器和消费电子产品。基于此类技术的设备必须具有低的人类和生态毒性。在设备使用寿命结束时，它们也应该是可生物降解的。事实上，如果我们考虑到物联网（IoT）所需的数十亿台设备，低环境影响是绝对必要的。最后但并非最不重要的是，设备必须坚固（例如可拉伸和可修复），因为它们可能位于偏远，难以进入的地区，如森林，并被放置在任意形状的物体上。***为了优化这些必须适应非刚性表面的器件的性能，必须同时进行机电材料表征。***该提案寻求为蒙特利尔大都市区的研究人员提供多功能基础设施的资金，这些研究人员涉及从可拉伸/柔性电子到生物电子和轻型电子等广泛领域。要求的基础设施是一个多轴机电测试仪，能够进行电气测量，结合高精度和多轴测试，包括压缩、拉伸、剪切、指数化和扭转。***有机电子材料是柔性、可拉伸和可修复电子设备中最通用的材料之一，因为它们结合了高导电性、水溶液处理、无氧化界面和抗腐蚀稳定性。另一个优点是可以通过微调沉积条件、衬底预拉伸或与其他聚合物混合来设计有机电子薄膜的机械性能。生物源有机材料具有有趣的电活性，生物相容性和生物降解性。***所要求的基础设施包括一个性别平衡的团队，由来自多个机构的四名处于不同职业阶段的研究人员组成，将支持可拉伸和可修复电子材料、元材料的机械性能和无害环境的电化学储能等研究项目。***由于其(i)处于物理化学、化学、生物医学和机械工程前沿的跨学科性质，（ii）具有产生从健康到环境影响加拿大人生活质量的高影响力科学和突破性技术的潜力，所要求的设备代表了一个特殊的机会，培养优秀的高素质人才，使他们成为未来新兴电子技术领域的领导者，结合高性能和可持续性。***********

Conformable and biodegradable electronic materials are central to human- and eco-benign technologies, including medical implants, food monitoring, wearable electronics, fieldable environmental sensors, and consumer electronics. Devices based on such technologies have to have low human- and eco-toxicity. They should also be biodegradable at the device-end-of-life. Indeed, if we think at the billions of devices required for the Internet of Things (IoT) low environmental impact is an absolute necessity. Last but not least, devices have to be robust (e.g. stretchable and healable) since they could possibly be located in remote, difficult-to-access areas, such as forests and be positioned on objects of arbitrary shape.***To optimize the performance of such devices that have to be adaptable to non-rigid surfaces it is imperative to have a simultaneous Electro-Mechanical materials characterization. ***This proposal seeks funding for versatile infrastructure open to researchers in the Montreal metropolitan area involved in a broad range of areas spanning from stretchable/flexible electronics to bioelectronics and light-weight electronics. The requested infrastructure is a Multiaxial Electro-Mechanical Tester, able to perform electrical measurements in combination with high-precision and multiple-axis testing in compression, tension, shear, indexation and torsion. ***Organic electronic materials are among the most versatile materials for flexible, stretchable and healable electronic devices, since they combine high conductivity, aqueous solution processing, oxide-free interfaces and stability towards corrosion. A further advantage of is the possibility to engineer the mechanical properties of organic electronic films via fine tuning the deposition conditions, substrate pre-stretching or blending with other polymers. Biosourced organic materials featuring intriguing electroactivity, biocompatibility and biodegradability are also available.***The requested infrastructure, involving a gender-balanced team of four researchers at different stages of their career, from multiple institutions, will support research projects on stretchable and healable electronic materials, mechanical properties of meta materials, and environmentally benign electrochemical energy storage.***Because of its (i) interdisciplinary character at the forefront of physical chemistry, chemical, biomedical and mechanical engineering, (ii) potential to produce high-impact science and ground-breaking technologies affecting the quality of life of Canadians from health to environment, the requested equipment represents an exceptional opportunity to train outstanding highly qualified personnel making them tomorrow's leader in the field of emerging electronic technologies combining high performance and sustainability.***********
