Motivated by their functional conformity, micro-cantilever-based MEMS oscillators are investigated in this study as structure-integrable transducers for the acquisition of guided ultrasonic waves in fiber–metal laminates. While acceleration-sen...

The urban acoustic environment is composed of a great variety of sounds, whose effects citizens are mainly unaware of, despite medical studies showing that urban noise affects quality of life and health, causing various problems from sleep disturbanc...

Automated damage detection in carbon fibre and fibre metal laminates is still a challenge. Impact damage is typically not visible from the outside. Different measuring and analysis methods are available to detect hidden damage, e.g., delamination or...

This issue of Engineering Proceedings gathers the papers presented at the 8th International Electronic Conference on Sensors and Applications (ECSA-8), held online on 1–15 November 2021, through the sciforum.net platform developed by MDPI [...]...

It is very challenging to estimate the accurate heart rate/beat during intense physical activities due to corruption of motion artifacts (MAs). However, it is difficult to reconstruct a clean signal and extract heart rate/beat from contaminated photo...

Flow sensors are essential for a variety of applications in fluidic industries. This paper proposes a liquid flow sensor using a microfluidic channel for macrotubular architectures. The sensor comprised a firm poly(methyl methacrylate) (PMMA) microfl...

In this work, molybdenum trioxide (MoO3) was synthesized and deposited on tapered optical fiber using the drop-casting technique for hydrogen (H2) detection at room temperature. A transducing platform in a transmission mode was constructed using mult...

Bilirubin (BR) is clinically confirmed as a biomarker for liver health and is used to assess the prognosis of cirrhosis. Optical and chemical methods have been utilized for blood BR biosensing. While optical methods offer real-time monitoring and are...

Recent studies show the possibility of using the sound information of an individual as the basis of a biometric security system. This paper introduces a soft wearable system that includes a miniaturized microphone and a wireless circuit for real-time...

Graphene oxide (GO) has the advantage of a uniform dispersion in water, which is essential for producing high-quality sensors. In this research, we monitor the production of a GO sensor by measuring the change in conductance of the aqueous GO during...
