What metrics can bioelectrical impedance analysis provide? Pt 1.

August 10, 2022 By Randy Frank Leave a Comment

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 […]

Barometric pressure sensor targets mobile device apps

April 5, 2022 By Redding Traiger

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?

February 23, 2022 By Randy Frank

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?

October 22, 2021 By Nikhil Agnihotri

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

March 1, 2021 By Redding Traiger

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 is the difference between an ECG, EEG, EMG and EOG?

March 28, 2019 By Randy Frank

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, […]
