Our earlier blog briefly introduced the topic of EEG artifacts. Basically, artifacts are noise sources that have overlaid onto the EEG and corrupted the purity of the brainwave signal when they are present. This is where noise filtering electronics, special materials and industrial design techniques are necessary to reduce noise influences. Two artifact types deserve… Read More»

When investigating applications for biosensors—particularly electrocardiograms—you’ll eventually come across two very common abbreviations: ECG and EKG. If you’re not familiar with these abbreviations, it can be tricky to determine which is which. However, once you know the difference between an ECG and an EKG, you’ll be well on your way to discovering what makes them increasingly valuable tools… Read More»

Merriam-Webster defines an algorithm as a step-by-step procedure for solving a problem or accomplishing some end. Algorithms can be developed for any process—from how to make your morning coffee to something as odd as establishing a friendship (diagram). In the biosensor world, you will hear phrases like EEG algorithms. What are EEG algorithms and what… Read More»

In our previous blog, we introduced the idea of EEG frequency bands, which can basically be described as a fixed range of wave frequencies and amplitudes over a time scale. These bands are components of the overall EEG waveform captured at an electrode. Scientists use mathematical models such as Fast Fourier Transforms to extract the… Read More»

Mobile and wearable devices have quickly become essential tools for consumers interested in tracking their health and fitness. As this technology becomes more accessible, manufactures will need to find ways to stand out in an increasingly crowded marketplace. As such, it’s critical to consider the different options available for biosensor technology that can enable wearable… Read More»

App stores such as iTunes and Google Play have completely revolutionized the way people consume information. There was a time, not long ago, when just about everything in an app store had a cost associated with it, but this is no longer the case. Now, consumers can enter an app store and download millions of… Read More»

ECG technology has been used by doctors for years to gather vital information on the health of their patients. In the past, this technology had to be used in controlled environments(e.g. in the Doctor’s office, Clinic or Hospital) in order to obtain the best results, and while nothing will ever replace the advice and information… Read More»
