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 […]

What’s new in sensors for smart homes: part 2
As noted in Part 1, some of the latest offerings for smart home sensors are based on sensor integration, technology, and connectivity. However, identified needs have created new applications that were not possible, simply not considered, or only offered for businesses — until recently. For example, the smart shelf was offered to retailers over 20 […]
What’s new in sensors for smart homes: part 1
In Cognitive Market Research’s recently published 7th edition of Home Smart Sensors Market Report 2024, the report’s author says the global home smart sensors market will witness significant growth soon. In addition to sensors for heating, ventilating, and air conditioning (HVAC) systems and lighting systems, sensors for safety and security are specifically addressed in the […]
How does voice recognition biometrics work?
A voiceprint, also called a voice template, is a unique pattern of a person’s voice sounds. Based on hundreds of subtle voice characteristics, voiceprints can be used to identify a person, just like fingerprints or facial recognition. The uniqueness of voiceprints derives from the fact that there are over 70 body parts, each of which […]
How does ASIL SEooC affect sensors?
Automotive systems that impact safety require adherence to the automotive functional safety standard — ISO 26262. Those electronic and electrical systems that are interlinked to use the input from one sensor to provide different functions in the automobile and minimize system cost, have additional safety considerations. To ensure proper and verified capability, the hardware (HW), software […]
How do eye & iris scan biometrics work?
Iris scan biometrics is one of two techniques that use unique eyeball characteristics for security and identification purposes. The other technique is retinal scanning. Iris scans are more commonly used because they are quicker and less invasive, but retinal scanning can be more accurate. The two techniques also have different applications. A retinal scan requires […]
What role does sensing play in detecting and analyzing garbage in the world’s oceans?
If you were not previously aware of the Great Pacific Garbage Patch (GPGP), viewing “Under Paris,” when it streamed on Netflix in the summer of 2024, provided painful awareness of a serious and growing problem — even though the movie was fantasy. “Under Paris” garnered over 69.6 million views in its premiere in June, making […]
How do fingerprint, finger geometry & vein recognition biometrics work?
Unique traits of fingers and hands are commonly used biometric markers. Those traits include fingerprints, finger vein recognition, hand recognition, and finger geometry. Hybrid identification systems have been developed that combine fingerprints and finger vein recognition. Artificial intelligence (AI) has recently been applied to fingerprint analysis, and it promises to increase its utility. Fingerprint and […]
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 […]
