With biosensing analog front end (AFE) ICs available from several major suppliers, researchers have a variety of options to investigate more sophisticated health measurement and monitoring techniques for healthcare professionals as well as users. Some of the applications currently under active investigation include identifying acute tissue injury and skeletal muscle fatigue, assessing neuromuscular disorders, tracking […]
Biometrics
What metrics can bioelectrical impedance analysis provide? Pt 1.
Healthcare and fitness are increasingly important to many people. The ease of making measurements or showing improvement metrics and the amount of data that can be provided by a minimal, non-invasive process makes the ongoing effort sustainable. Bioelectrical impedance (or bioimpedance) analysis (BIA) provides users with a technique that is easily integrated into smart watches […]
Ultra-low-noise barometric pressure sensors target smart home appliance apps
TDK Corporation announces that the InvenSense ICP-20100, the latest generation of the SmartPressure MEMS Barometric Pressure Sensors, is now in mass production and has been certified by NextNav. Launched in 2021, the NextNav Certified process independently verifies the InvenSense sensor accuracy measurements, by engaging directly with component manufacturers to rigorously test sensors in real-world operating […]
Barometric pressure sensor targets mobile device apps
Bosch Sensortec introduces the BMP581, a barometric pressure sensor that couples low power consumption with extreme accuracy to provide altitude tracking in wearables, hearables, or IoT devices. This capability makes it ideal for applications such as fitness tracking, fall detection, indoor localization, and navigation, enabling new use cases that were previously impossible. This extreme level […]
How is biomarker sensing expanding?
Pathogens, infectious agents that cause disease, can include microscopic viruses, bacteria, fungi and protozoa. Both biomarkers and biosensors can detect and identify pathogenic agents. After using biomarkers to measure and detect pathogenic factors and assess biological conditions., drugs can be delivered to the target tissue so that other tissues are not damaged. Biomarkers are widely […]
What are different types of biometric sensors?
The term “Biometrics” is derived from “bio’” which means life, and “metrics”, which means measurement. Biometrics is developing for use in various technologies, including the unique identification and recognition of people. The technology at its current juncture is widely used in security and surveillance systems. Biometrics also has the possibility of converging with other technologies […]
4-in-1 MEMS sensor measures gases, humidity, temperature and barometric pressure
Whether at home, in the office, or outdoors, we need to be confident that the air around us is clean and safe to breathe – COVID-19 has clearly highlighted the importance of air quality. Due to the particulates, gases, and even airborne viruses ubiquitously present in our modern environment, poor air quality has an increasingly […]
What makes a winning sensor?
At Sensor Expo 2019 in San Jose, CA, Travis Taylor, an Associate MTS at Maxim Integrated, demonstrates the Health Sensor Platform 2.0 that won the Sensors Expo 2019 Innovative Product of the Year Award. It can measure electrocardiogram (ECG), optical heart rate and temperature. In addition to its wrist-worn display, the measured information can be […]
What is the difference between an ECG, EEG, EMG and EOG?
An electrocardiogram (ECG or EKG), electroencephalogram (EEG), electromyogram (EMG) and electrooculogram (EOG) all measure biopotentials, the electrical output of human activity. However, the amplitude and bandwidth of the measurements vary for each of these. The table shows the values for each biopotential group according to the article “Biopotentials and Electrophysiology Measurements” in The Measurement, Instrumentation, […]
Hall effect 3D position sensors allow active stray field compensation
TDK Corporation expands its Micronas position sensor portfolio with the Hall effect sensor family HAL 39xy featuring stray-field compensation capability built on the highly flexible architecture for multidimensional magnetic-field measurements marketed under the trademark masterHAL. The sensors meet today’s and tomorrow’s automotive and industrial market needs and offer four different measurement modes in a single […]
