Optics11 will demonstrate world’s only fiber optic Acoustic Emission system OptimAE. As fiber optic systems have some specific advantages over electric systems, like the immunity to liquids and/or strong EMI fields, the system will show the measurements capabilities of our fully passive sensors as they are facing such conditions.

Metis Design Corporation will demonstrate their novel carbon nanotube (CNT) based potential drop (PD) fatigue crack gauge. This sensor does not employ any cables, connectors or batteries, and is able to reliably track cracks in any material starting from ~1mm. An active RFID architecture is used to momentarily power the system to remotely acquire data and indicate the current crack length in real-time. A fiberglass test article will be loaded in tension to grow a natural crack in this live demonstration, while crack length is displayed on a laptop a meter away.

In this demonstration, the most updated human-structure interface enabled using Augmented Reality will be shared through a series of examples including, but not limited to: crack measurement, human-robotic interaction, time machine, downsizing, and more. The Smart Management of Infrastructure Laboratory (SMILab) has been collaborating with the Engineering Institute of Los Alamos National Laboratory developing Augmented Reality for Structural Inspection since Fall 2016. click Here for the website of SMILab at the University of New Mexico. | |

The IIoT is a powerful tool in SHM. The beggining of my presentation is the brief description of IIoT in terms of developed real-time remote monitoring system. The key part of the presentation is to show the remote monitoring web client in action. The emphasis is placed on trend view tool, operator screen display and analysis tile, which contains the time-frequency and polar graph display. The analysis is made using the rotational blade vibration data, however there is no limitation to use for SHM. The demonstration is largely in video format. To sum up the demonstration will show how the user can easily monitor simultaneously a number of structures geographically located in different locations from the main station only using the internet connection. click Here for the website of NTIS – New Technologies for the Information Society. | |

Occupant monitoring is an important aspect of many smart building applications such as smart healthcare and efficient energy management. Current sensing approaches for occupant monitoring (e.g., pressure-based, vision-based, and mobile platforms) either require dense deployment, have privacy concerns, or need the occupants to carry or wear a device. To overcome these limitations, we introduce a new sensing approach using footstep-induced floor vibrations. The main intuition is that occupants’ activities (e.g., walking) cause the structure to vibrate. These vibrations travel through the structure and we receive them in our vibration sensors. In this demo, we will introduce and describe our sensing system and the data acquisition system. Then, we describe and show some of the applications in occupant monitoring such as occupant localization and detection. | |

We will showcase a video of the inspection robotics that we have developed (related to our manuscript, "Infrastructure Mapping and Inspection using Mobile Ground Robotics"). Our video/presentation will show footage of real-world data collection using our robots, automated processing, and inspection results. Our video/presentation will combine existing footage (e.g., https://www.youtube.com/watch?v=YCihWIBIGZ8) with new footage which focuses on results obtained using our platform. | |

Luna Innovations will demonstrate how high definition fiber optic sensing (HD-FOS) can provide more data and insight for SHM applications. The demo will show Luna ODiSI system acquiring real-time strain profiles, with sub-millimeter spatial resolution, of a carbon fiber composite structure. Either surface-mounted or embedded within the structure’s material, high-definition strain measurement can detect damage and unexpected events. The data will also be visualized contextually by mapping the live data directly to a 3D model of the instrumented sample. Click here to access Luna Innovations Website. |
The focus of the workshop is to promote applications of SHM technologies and to encourage interaction between industry and academia. We place significant emphasis on industrial applications including aerospace, ground transportation systems, and civil infrastructures. Your company plays a leading role in this field and is cordially invited to participate in a special session, SHM in Action, which provides a unique opportunity to combine product demonstration with podium discussion.

Procedure:
The session intends to show as many demonstration cases as possible, addressing the aspects mentioned below:
Each presentation is allowed no more than 5 minutes through a video, internet or a hardware live demonstration only, which will be directly displayed to the audience on a large screen. It is mandatory that the SHM system is shown in action. Static displays are not acceptable and live demonstrations are preferred over videos. Each presentation will be followed by a brief Q&A session where the SHM demonstrators will answer questions from the audience.
The test cases being presented can be either based on self-developed or purchased SHM systems. The source of the SHM hardware is eligible to be mentioned but no further advertisement from or about the supplier of the SHM system will be accepted.

Digital Twins Lab, a joint research team from Stanford (USA) and Chalmers (Sweden), will demonstrate the creation of a Digital Twin for a concrete beam in a live demo. Digital Twin of an infrastructure is a living digital simulation that brings all the data & models together, and updates itself from multiple sources to represent its physical counterpart. We will demonstrate an innovative solution in which next-generation Autonomous Data Collection, Data-Driven models and Physics-Based models are integrated to a Digital Twin framework to create a comprehensive SHM system for condition assessment of infrastructures. The will demo include: (1) Data Collection: real-time 3D scanning of a cracked concrete beam using a 3D structured-light scanner, (2) Crack Detection: real-time crack detection using an AI-based algorithm, and (3) Simulation: real-time incorporation of the detected crack into FE model, and real-time FE simulation.

Seismic structural health monitoring of structures is critical to not only provide early warning of seismic motions but also enable rapid structural condition assessment for informed decisions. Wireless smart sensors are an attractive alternative to expensive and difficult-to-deploy wired monitoring systems, as they significantly reduce deployment and operating costs. However, seismic structural monitoring using smart sensors faces obstacles that include stringent energy constraints and limited transmission bandwidth. We will showcase an intelligent wireless system for real-time seismic monitoring of civil infrastructure. The event-driven system consists of three main components: ultralow-power on-demand sensing prototypes, a high-throughput live streaming framework, and a graphical user interface for real-time damage assessment. We will demonstrate that the system can detect seismic motions, provide high-quality synchronized data, and present damage assessment in real-time. Specifically, the demo will include: (1) real-time interstory drift estimation of a 6-story building model under a seismic event, and (2) sudden damage detection of the building model under a seismic event.
