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 […]
Biometrics
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 […]
What vital signs can be monitored with your thumbs?
At CES2017, Yenfang Koh, a Marketing & Operations Analyst from Mocacare, explains how the company’s Mocaheart can scan both thumbs for blood oxygen and electrocardiogram (EKG) measurements. The readings provide heart rate and blood (pulse wave) velocity that correlates to blood pressure.
