For portable and embedded smart, wireless electronic systems, energy harvesting from the
ambient energy sources has gained immense interest in recent years. Several ambient …

In location management, the trajectory represents the motion of a moving object in 3D space-
time, ie, a sequence (x, y, t). Unfortunately, location technologies, cannot guarantee error …

In recent years, the Helmholtz resonator and membrane are two popular elements that have
been vastly employed in the design of energy harvesters and metamaterials. In this paper, a …

This paper reports an improved acoustic energy harvester with a tapered Helmholtz cavity.
The harvester consists of a bimorph piezoelectric composite plate and a Helmholtz …

Acoustic piezoelectric energy harvesters in quarter-wavelength resonator tubes undergo
linear resonant vibration due to the external force. However, the variation of environmental …

This paper presents a study of recent development in the field of acoustic energy harvesters
(AEHs) technique and the maximum power generated from each of these techniques. AEHs …

This paper presents the development of a broadband, multi-frequency acoustic energy
harvester. The devised energy harvester contains an optimized Helmholtz resonator with …

The development of an electromagnetic-based acoustic energy harvester using Helmholtz
resonator is reported in this paper. The working principle, fabrication and characterization of …

To harvest acoustic energy from urban railways, a novel and practical acoustic energy
harvester is developed. The harvester consists of a piezoelectric circular plate and a …

A class of piezoelectric energy harvester is presented to harness the vibration energy from
coupled acoustic-structure systems such as those existing, for example, in aircraft acoustic …
