The overall vision of the project is to develop comprehensive knowledge and an innovative methodology in the areas of energy autonomous wireless systems from a global system perspective, enabling self-powered, battery-free wireless sensing nodes to meet a wide range of structural health monitoring (SHM) applications. The research vision builds on the project partners' complementary skills and strengths in the area of 'towards zero -power ICT' with the potential to lead to multiple scientific and technical breakthroughs. The first breakthrough is to make use of the SHM sensing device itself to implement a single multifunctional device providing both structural health data and electrical energy harvested from mechanical vibrations. Another breakthrough will be to store the harvested energy in a fully integrated smart storage device, which adapts its storage capacity, according to the available energy in the environment and to the power consumption of the load. This adaptability will provide a constantly optimized matching between storage device and energy harvester to foster energy transfer. The energy storage itself will be a micro-ultracapacitor, so will have the desirable features of high specific energy, short time response, long lifetime and safe operation. This micro -ultracapacitor will be implemented in a silicon compatible technology so as to facilitate co-integration with other functions. Moreover, to drastically reduce the power consumption of the communication module, the proposed strategy is based on using impulse radio UWB (ultra-wideband) and dark silicon design approaches. A final innovation will be the co-location of the different devices (harvesting, sensing, storage, processing, data transmission) on the same flexible substrate, in order to enable conformal attachment of the device, a characteristic highly desirable in a SHM context wher e the surfaces to be monitored are seldom planar. Additionally, by this means the issue of the anisotropy of vibration harvesters is settled, the harvester being, by nature, properly oriented. More globally, the project aims at producing a device in which co-integration, co-location of functions, versatility of applications and energy autonomy are pushed to a maximum.

该项目的总体愿景是从全球系统的角度从能源自动无线系统的领域发展全面的知识和创新方法，从而使自动化的，无电的无线无线传感节点能够满足各种结构性健康监测（SHM）应用。研究愿景以项目合作伙伴的“互补技能和优势”为基础，该领域有可能导致多个科学和技术突破。第一个突破是利用SHM传感设备本身来实现单个多功能设备，从而提供结构性健康数据和从机械振动中收获的电能。另一个突破将是将收获的能源存储在完全集成的智能存储设备中，该设备根据环境中的可用能量和负载的功耗来适应其存储容量。这种适应性将在存储设备和能量收割机之间不断优化的匹配，以促进能量转移。能源存储本身将是微型脱甲表面，因此具有高特异性能量，短时间响应，长寿命和安全操作的理想特征。该微甲状腺胶囊剂将在硅兼容技术中实施，以促进与其他功能的协整。此外，为了大大降低通信模块的功耗，提出的策略是基于使用Impulse Radio UWB（超宽带）和Dark Silicon设计方法的基础。最终的创新将是在相同的柔性基板上的不同设备（收获，传感，存储，处理，数据传输）的共同点，以便使设备的保形附件很少被监测的SHM上下文中高度可取的特征。此外，通过这种方式，振动收割机各向异性的问题就解决了，从本质上讲，收割机是正确定向的。在全球范围内，该项目旨在生产一种设备，在该设备中，将功能，应用程序多功能性和能量自主权的共整合，功能的共同点和能量自主权最大程度地推向了最大程度。
