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.***********

适形且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、食品监测、可穿戴电子产品、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较低的人类和生态毒性。它们还应该在设备报废时可生物降解。事实上，如果我们考虑到物联网 (IoT) 所需的数十亿台设备，那么低环境影响是绝对必要的。最后但并非最不重要的一点是，设备必须坚固耐用（例如可拉伸和可修复），因为它们可能位于森林等偏远、难以到达的区域，并可能放置在任意形状的物体上。***为了优化此类必须适应非刚性表面的设备的性能，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开放的多功能基础设施提供资金，这些基础设施涉及从可拉伸/柔性电子产品到生物电子产品和轻型电子产品等广泛领域。所需的基础设施是多轴机电测试仪，能够执行电气测量以及压缩、拉伸、剪切、索引和扭转方面的高精度多轴测试。 ***有机电子材料是柔性、可拉伸和可修复电子设备最通用的材料之一，因为它们结合了高导电性、水溶液加工、无氧化物界面和腐蚀稳定性。另一个优点是可以通过微调沉积条件、基材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。还提供具有令人着迷的电活性、生物相容性和生物可降解性的生物源有机材料。***所要求的基础设施包括来自多个机构、处于职业生涯不同阶段的四名研究人员组成的性别平衡团队，将支持可拉伸和可修复电子材料、超材料的机械性能以及环境友好的电化学储能方面的研究项目。***由于其 (i) 物理化学、化学、生物医学和机械工程前沿的跨学科特征，(ii) 产生影响加拿大人从健康到环境的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培训优秀高素质人才的绝佳机会，使他们成为结合高性能和可持续性的新兴电子技术领域的未来领导者。************
