The bulkiness of traditional batteries, as well as frequent charging and electronic detritus
caused by the replacement of old batteries, hinder the ability of low-powered electronic …

This paper discusses piezoelectric acoustic devices based on widely used piezoelectric
materials. Commonly used piezoelectric thin film deposition techniques and the influence of …

This review collates around 100 papers that developed micro-electro-mechanical system
(MEMS) capacitive microphones. As far as we know, this is the first comprehensive archive …

This paper reports a review about microelectromechanical system (MEMS) microphones.
The focus of this review is to identify the issues in MEMS microphone designs and …

Understanding the effect of doping concentration on the various properties of metal-doped
ZnO nanoparticles (NPs) near the shape transition point (sphere to the rod) is essentially …

Persistent poor acoustic conditions can imbalance humans' psychophysical capabilities. A
good acoustic project starts with either correct measurements of the existing acoustic …

In this paper, we characterize and model a bidirectional front-end based on pseudo-floating
gate amplifier (PFGA) for actuation and read-out of resonating sensors. The basic idea …

This paper reports the aluminum nitride (AlN) based piezoelectric MEMS acoustic sensor for
aeroacoustic applications. The acoustic sensor reported, is square diaphragm based, which …

Electret microphone is a device that is used as a detector to record the indirect
photoacoustic (PA) signal. Most of the PA spectrometers contain a sensitive electret …

Acoustic sensors are extensively used in recent days not only for sensing and condition
monitoring applications but also for small scale energy harvesting applications to power …
