The last decade has witnessed significant advances in energy harvesting technologies as a
possible alternative to provide a continuous power supply for small, low-power devices in …

In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

An impedance-matched surface has the property that an incident wave generates no
reflection. Here we demonstrate that by using a simple construction, an acoustically …

Recent advances in the field of low-power electronic components production have spurred
research in energy harvesting. Ambient sound can be used as a source of energy, and the …

This paper investigates the design and analysis of a novel energy harvesting device that
uses magnetic levitation to produce an oscillator with a tunable resonance. The governing …

Piezoelectric energy harvesting has attracted wide attention from researchers especially in
the last decade due to its advantages such as high power density, architectural simplicity …

Multifunctional materials are highly desired for the design of compact engineering structures,
such as aircraft where weight reduction, sound absorption, load carrying, and energy …

Acoustic energy is mostly wasted without a proper energy harvesting approach. In this work,
an integrated triboelectric nanogenerator (TENG) with a polymer tube is constructed to …

Wireless sensor nodes (WSNs) and embedded microsystems have recently gained
tremendous traction from researchers due to their vast sensing and monitoring applications …

Nanoscale spacecrafts have shed light on an audacious but promising vision for interstellar
travel to neighboring planets beyond the solar system. The nanocrafts can be accelerated to …
