Abstract We present a novel internet of things (IoT) sensing platform that uses helical propagation paths of ultrasonic guided waves (UGWs) for structural health monitoring. This wireless sensor network comprises multiple identical sensor units that

Pipe fouling is a challenging problem in many industrial applications. Current cleaning techniques require halting the production during the cleaning phase and the existing methods are unable to do targeted cleaning, even though fouling is often loca

Ultrasound provides a way to clean fouled pipes in industrial settings without interrupting the production. Ultrasonic clamp-on cleaners are used to clean pipes, but they typically cannot focus the cleaning power. This leads to insufficient cleaning

Time-reversal (TR) is method to focus acoustic energy inside complex media. TR focusing to a predefined target point requires either an echo from a target point with acoustic impedance contrast or direct impulse actuation at the target point. Here, w

Time reversal (TR) is a technique based on the reciprocity principle of the wave equation that can be used to focus waves. In an enclosed system, comprising homogenous medium that includes no reflecting targets, it normally is impossible to use time
