Description
The emWave PC Ear Sensor is for use with the discontinued USB POD. This sensor has excellent signal quality, even under difficult conditions. Sleek design is comfortable for extended wear and fits all sizes (child to adult).
USB Ear Sensor has a more compact profile and lightweight construction for a more user friendly sensor. Greater sensitivity, easier ear placement, accommodates varying sizes more readily and it's longer, more flexible cord allows for freedom of movement.
Requires and plugs into the new USB Sensor Pod, which is included in the full emWave PC package, available in the USB Sensor Hardware Package and also sold separately.
Glossary of Terms
Cardiac Coherence--A mode of cardiac function in which the heart?s rhythmic and electrical output is highly ordered. HeartMath research has shown that the positive emotions such as love, care, and appreciation increase coherence in the heart?s rhythmic beating patterns. During states of cardiac coherence, brain wave patterns have been shown to entrain with heart rate variability patterns; in addition, nervous system balance and immune function are enhanced. Overall, the body functions with increased harmony and efficiency.
Coherence--Logical connectedness, internal order, or harmony among the components of a system. This term can also refer to the tendency toward increased order in the informational content of a system or in the information flow between systems. In physics, two or more waveforms that are phase-locked together (so that their energy is constructive) are described as coherent. Coherence can also be attributed to a single waveform, in which case it denotes an ordered or constructive distribution of power content. Recently, there has been a growing scientific interest in coherence in living systems. When a system is coherent, virtually no energy is wasted, because of the internal synchronization among the parts. In organizations, increased coherence enables the emergence of new levels of creativity, cooperation, productivity, and quality at all levels.
Heart Rate Variability (HRV)--The normally occurring beat-to-beat changes inheart rate. Analysis of HRV is an important tool used to assess the function and balance of the autonomic nervous system. HRV is considered a key indicator of aging, cardiac health, and overall well-being.
Stress--Pressure, strain, or a sense of inner turmoil resulting from our perception and reactions to events or conditions. A state of negative emotional arousal, usually associated with feelings of discomfort or anxiety that we attribute to our circumstances or situation.
