Evaluation of Thermal Damage in Pipe by Nonlinear Guided Wave
Abstract: This work investigates the evaluation of thermal damage in aluminum pipe by using nonlinear guided wave. Thermal loading was imposed on the specimens to cause thermal degradation. Flexible Polyvinylidene Fluoride (PVDF) comb transducers are used to generate and receive the ultrasonic waves. The second harmonic wave generation technique was used to check the material nonlinearity change after different heat loading. Conventional linear ultrasonic approach based on the acoustic attenuation was …

Footstep Power Generation Using Piezoelectric Materials: A Renewable Approach for Smart Infrastructure
Abstract: The rapid depletion of fossil fuels and the increasing global demand for sustainable energy have necessitated the development of decentralized energy harvesting systems. This paper presents a comprehensive study on footstep-based power generation using piezoelectric materials as a viable renewable energy solution for smart infrastructure. The proposed system converts mechanical energy generated from human locomotion into electrical energy using optimized piezoelectric transducer arrays integrated beneath floor tiles. The study covers …
