The device has an LED that sends light into the tissue and records how much light is either absorbed or reflected to the photodiode (a light-sensitive sensor). As the blood pulses into the tissue, more light is absorbed – as the blood flows away from the tissue, more light is reflected...
Biometric data storage involves three components: a sensor to collect input data, a computer to process and save it, and software to act as a go-between. The sensor records your biometric information, which is then converted into a digital format,encrypted, and sent to long-term storage. Whe...
This is part of a paradigm shift within human behavior research (be it within psychology, neuromarketing, or any field that studies human behavior). By using concrete measurements of human physiology, the reliability of findings has never been stronger, and each biometric sensor provides a different...
If a signal is generated from a single sensor or source, it is called a single channel signal. Example ECG signals. Signals are generated by multiple source or multiple sensor. This signals, can represented in vector form. Example: ECG (Electrocardiogram) are often used 3-channel and 12- ch...

deforms crystals. Gabriel Lippmann, a Franco-Luxembourgish physicist, is credited with the inverse effect discovery the following year, which led to his invention of the Lippmann electrometer in 1883, a device at the heart of the operation of the first experimental electrocardiography (ECG) machine...
While the ECG measures the electrical activity of the heart, the PPG detects the change in blood flow to the tissue. An ECG thus directly measures the heart rate, while a PPG sensor detects the pulse rate.59 Where is the pulse rate measured?
