Chapter 1Introduction

De Ponti, Jacopo Maria

Pages: 1 –6

[In recent years the world is facing an extraordinary diffusion of the Internet of Things (IOT) concept which is the idea of building smart and autonomous sensors networks which can help us in sensing, understanding and controlling our environment. For this idea to be effective, new sensors...

Chapter 2State-of-the-Art of Engineered Materials for Energy Harvesting

De Ponti, Jacopo Maria

Pages: 7 –25

[This chapter contains a brief presentation of structuring materials and metamaterials proposed in literature for vibration-based energy harvesting. The following systems are considered: Parabolic Acoustic Mirror (PAM), Resonant defect inside a Phononic Crystal (PnC), Acoustic Funnel,...

Chapter 3One-Dimensional Inhomogeneous Media

De Ponti, Jacopo Maria

Pages: 27 –60

[This chapter analyses one-dimensional inhomogeneous media through lumped models. Basic concepts on wave propagation in homogeneous and inhomogeneous media are introduced for both periodic and aperiodic structures. An interpretation of the most common linear wave propagation mechanisms is...

Chapter 4Graded Elastic Metamaterials

De Ponti, Jacopo Maria

Pages: 61 –89

[This chapter analyses the problem of wave propagation in elastic continua, with specific reference to plates and half-spaces. Wave propagation in thin elastic plates and half-spaces is studied going from classic analytical theories to numerical (FEM) models able to describe the interaction of...

Chapter 5Advanced Multiresonator Designs for Energy Harvesting

De Ponti, Jacopo Maria

Pages: 91 –120

[This chapter, starting from basic concepts on piezoelectric materials, explores piezo-augmented arrays of resonators able to dramatically increase the energy available for harvesting, and the operational bandwidth. Specifically, three designs are proposed, exploiting rainbow reflection,...
