A 3D Printed Architecture Sensor for Structural Health Monitoring

Structural health monitoring using vibration sensors is critical for ensuring human safety. To address these challenges, we have developed a highly sensitive, cost-efficient, sustainable, and widely accessible monitoring system using a 3D-printed vorticella-kirigami-inspired (VK) structure. Our system includes wireless 3D-printed portable sensors with an Internet of Things (IoT) setup, which detects impacts on potentially fragile building components even when they occur at the epicenter. The VK structure has been customized for a response at around 2 Hz, with superior sensitivity of 7.85 pF/g. To make our system more practical, we have implemented the Internet-of-Things protocol which enables real-time or saved vibration data access using multiple smartphones and personal computers without distance restrictions. Our IoT structural health monitoring system presents a promising approach for more active utilization of building health monitoring systems.
