Today’s cuff technique for measuring blood pressure (BP) goes back 100 years or so. While the sensors used to measure pressure have changed considerably, the inflate, deflate, and then-measure approach is quite similar. It has even been automated for home use. However, it is not a continuous measurement. In contrast, researchers are exploring several continuous, […]

How are VCSELs used in biomedical sensors?
Vertical-cavity surface-emitting lasers (VCSELs) are used in biomedical sensors because they emit highly focused, coherent light at specific wavelengths, enabling precise detection and analysis of biomolecules. Applications include blood oxygen level monitoring, optical coherence tomography (OCT) for imaging tissue structures, fluorescence microscopy, and analysis of live biomolecules in lab-on-a-chip systems. VCSELs offer a third option […]

EEG sensing can improve driving safety.
How do facial recognition biometrics work?
Facial recognition biometrics is an advanced form of image recognition based on artificial intelligence (AI) and machine learning (ML). It can be used on still or video images. This article begins by discussing the basics of facial recognition, including facial detection and feature extraction using convolutional neural networks (CNNs). It then moves on to consider […]
How do ear recognition biometrics work?
In the era of face masks, ear recognition can provide a viable alternative to more commonly used facial recognition. The human ear remains relatively unchanged, making it suitable for security authentication applications. It can also be easier to extract information from since it is not subject to variations like facial expressions. Ear recognition biometrics analyze […]
How do body odor recognition biometrics work?
A body odor recognition system uses an electronic nose (E-nose) with numerous chemical sensors to detect and identify volatile organic compounds (VOCs) in the air. General-purpose E-noses are available to detect and identify complex chemical mixtures that constitute aromas, odors, fragrances, and formulations. Breathalyzers are specialized E-noses used to measure the amount of alcohol in […]
