How IoT Sensors Detect Micro-Cracks in Concrete Before They Widen
Concrete cracks are inevitable — but what if you could detect them when they're still microscopic, before they become structural problems? In this episode, Lucas and Luna explore how IoT-enabled acoustic emission sensors are catching micro-cracks in concrete bridges, dams, and buildings. They look at the physics — how sensors pick up ultrasonic energy released when a crack forms — and a real deployment on the I-35W Saint Anthony Falls Bridge in Minneapolis, where over 200 sensors monitor for crack initiation. The hosts also discuss the cost: about $400 per sensor node, versus millions in…
