Abstract: This paper reports on the fabrication of a complementary metal oxide semiconductor (CMOS)-based 20 × 20 amperometric sensor array integrated with boron-doped diamond (BDD) microelectrodes.

Then, the sensor current was measured employing the controlled potential amperometric technique for each of these level combinations, which were obtained via chemometric strategies. The Pareto chart ...

The Core 2 sensor attaches to a heart rate monitor to keep tabs on your body temperature during workouts, the better to understand how the heat is affecting you. I found it a little fussy to set ...

Then, the voltage is reversed, causing the lead to come off the sensor and produce an electrical current. The strength of this current indicates how much lead is in the water sample. If lead is ...

A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use of spin defects in hexagonal boron nitride (hBN) as powerful, room ...

The Canon EOS R6 Mark II gets plenty of mileage from its 24MP full-frame CMOS sensor. Picture quality is excellent, even at higher ISOs, and the autofocus system rarely misses its target thanks to ...

The Sony ZV-E10 II is the best camera for vloggers, edging Fujifilm’s new creator model the X-M5 thanks to the superior autofocus. It comes with a 26-megapixel APS-C sensor that’s much faster ...

How do ECG smartwatches work? Most watches have a built-in ECG sensor, that can take a spot reading of your heart rate rhythm. You start the app and then place your finger on a specific part of ...

Compact cameras have become popular again in the last couple of years. And you can buy full-frame-sensored compact cameras - such as the luxury-priced Leica Q3 - but to keep them relatively compact ...
