Non-Contact Body- and Head-Based Monitoring of Brain Electrical Activity

摘要

In the human brain, using electrodes or other sensors placed close to the part of the body below the head to create a raw signal that penetrates the hair and clothes without physically touching the body Apparatus and method for monitoring the electrical activity of a patient ("brain wave"). In addition, devices and methods for monitoring electrical activity ("brain waves") in the human brain utilize non-contact sensors placed close to a portion of the head to create a raw signal. Do. The raw signal is filtered to generate an analysis signal that includes frequency components associated with brain electrical activity, and the irrelevant frequency components are attenuated. The device and method can be used for biofeedback-based attention training, human ability training, gaming, biometrics, cognitive status detection and relaxation training. In order to perform signal processing tasks and analysis functions, either wired or wireless signal connections are made to electronic circuitry, typically comprising a digital computer.
