This paper reports on a gas sensor based on two bulk acoustic wave (BAW) resonators electrically coupled with a tuneable capacitor. The weak coupling strength was tuned to its optimal value (achieving maximum sensitivity) by varying the capacitance (...

In this work, we present a simple, fast, and cheap procedure for the determination of mercury [Hg(II)] by square wave anodic stripping voltammetry (SWASV) at nanocomposite screen-printed graphite electrodes. The nanocomposite surfaces were obtained b...

The loss of the sense of smell has not produced as many technological developments to mitigate the inconvenience it causes compared to the loss of vision or hearing. Anosmia or hyposmia concerns approximately 20% of the current European population an...

High energy radiation is known to potentially impact silicon-based optical sensors adversely, either permanently or reversibly [...]

This study introduces a portable gold-nanoparticle-enhanced surface plasmon resonance (SPR) biosensor for the swift and highly sensitive detection of β-bungarotoxin in krait venom. Demonstrating a 10³-fold increase in sensitivity over traditiona...

Neuroaesthetics is a relatively young field that connects neuroscience with empirical aesthetics and originates in the neurological theory of aesthetic experience. It investigates brain structures and activity during the phenomena of artistic percept...

Exposure to hazardous gases like NO_x can have a negative impact on our health. High-performance sensors are needed to control high levels of these contaminants, which, in most cases, are generated by automotive exhaust or industrial factories. In thi...

Exposure to hazardous gases like NOx can have a negative effect on our health. High-performance sensors that are also able to sustain harsh environments are needed to control high levels of these contaminants, which in most cases, are generated by au...

Miniature drones for indoor use and stationary sensor nodes have been equipped with thermal imaging and sensors for temperature, humidity, and relevant gas components to enable preventive analysis of indoor environments in order to identify pre-fire...

We demonstrate the systematic optimization of SnO₂-based thin-film chemical sensors by using mono-, bi- and tri metallic nanoparticles (NPs) composed of Ag, Pd, and Ru, which are deposited via magnetron sputtering inert gas condensation. The ultrathi...
