This book provides a comprehensive and practical examination of advanced piezoelectric energy harvesting technologies designed for smart road applications. It presents a complete pathway from innovative device design and theoretical analysis to laboratory validation, system integration, and field implementation. The work uniquely compares and develops three distinct technological approaches: multi-layer synergistic cantilever, stroke-amplified cantilever, and stacked piezoelectric systems, offering scenario-specific solutions. Its scope thoroughly covers not only the energy harvesters themselves but also critical supporting technologies, such as power management circuits and construction methods for real-world pavement integration. Serving as an essential resource for researchers, civil engineers, and graduate students in the fields of smart infrastructure and sustainable energy, this book establishes a foundational framework for developing self-powered smart roads, directly supporting the advancement of low-carbon, intelligent transportation infrastructure.
