Wearable/Wireless | 3D Seismocardiography

Researchers have been investigating the use of a promising, yet not entirely understood technique known as seismocardiography. This method takes advantage of natural vibrations produced by the cardiovascular system by recording with accelerometers,…
Surface EMG | Exercise and Muscle Fatigue

Electromyography (EMG) has long been the clinical and research standard for skeletal muscle activity. Through manipulations of waveforms produced by electrical signals given off by muscle movement, researchers can gain insight into the mechanical…
Wireless, Wearable | Quality of Life Technologies

There is a major concern growing in the medical community that the ratio of health workers to population size is decreasing. This means that the number of available doctors and medical professionals is starting to become too small to handle the number…
Data Logging | Understanding Social Fear Learning
Social
fear learning seems like a fairly straightforward subject. A person observes
another reacting or expressing through either verbal or nonverbal cues that a
stimulus makes them fearful or afraid. Surprisingly though, little is known
…
ECG Analysis | Physiological Benefits of Low-Altitude Tourism

There
is a reason people call it “the Great Outdoors.” People often escape to nature
to relax and recharge from the stressors of suburban life. Wilderness tourism
has been and will probably continue to be very popular. Permit requests to
…
Data Logging | Lumbar Multifidus (LM) Muscle

The lumbar multifidus (LM) muscle
is an important muscle that works to stabilize certain spinal segments as well
as control the extension moment of the lumbar spine. Studies have shown that
this muscle can be atrophied in people with…
Surface EMG | Musician’s Cramp

Focal hand dystonia, also known as “musician’s cramp,” is a movement disorder that causes involuntary flexing in the fingers, or finger cramps, when playing a musical instrument. This disorder poses a huge problem for professional musicians and in…
ECG Analysis | Body Dissatisfaction in University Attending Women

Weight
and body shape issues are a major concern amongst today’s general population,
especially young women. The pressure from outside forces to conform to a certain
body type, whether it is from advertisements or even their own social media
pages,…
ECG Analysis | Physiological Changes in Response to Reporting

Physiological
responses can offer researchers key insights into the mental state of their
participants. Whereas human subjects can lie or misreport their emotions on a
self-report questionnaire, their physiological signals show the actual
truth.…
Wireless Physiology | Psychophysiological Measures of Emotion

Emotional reactions influence, and may help predict, our decisions and
offer valuable information for communication and neuromarketing researchers, but
emotion is difficult to measure explicitly. Emotional responses are complex
phenomena consisting…
Data Logging | Improvements in Wireless Wearables for Physiology Research

Researchers have long recognized the need for a better tool for Electroencephalogram
(EEG) ambulatory monitoring. While many have come up with certain wired
solutions, there has not been a valid solution for long term logging or
telemetry.…
ECG Analysis: VLPs | Data Acquisition

An electrocardiogram (ECG or EKG) is a graphical recording of the changes occurring in the electrical potentials between different sites on the skin as a result of cardiac activity. The electrical activity of the heart is a sequence of depolarizations…
ECG Analysis of Putting Tournament

An electrocardiogram (ECG; a.k.a.
EKG) recording can be extremely useful for analysis of a variety of
physiological studies. When combined with automated ECG analysis software,
researchers can identify ECG intervals, assess heart rate variability…
