BioZen
BioZen is one of the first mobile applications to provide users with live biofeedback data from multiple wearable body sensors covering a range of biophysiological signals, including electroencephalogram (EEG), electromyography (EMG), galvanic skin response (GSR), electrocardiogram (ECG or EKG), respiratory rate, and temperature biofeedback data and display it on a mobile phone.
BioZen was developed as a pilot project to study the feasibility of using smartphones to receive signals from biosensor devices. The National Center for Telehealth & Technology (T2) is a Department of Defense organization that evaluates new technologies for telemental health. BioZen represents an approach to mobile monitoring of biosensor devices that may be further developed to support future projects. No further development or enhancements to BioZen are planned.
Using BioZen requires compatible biosensor devices (see listing below). These devices and BioZen are not designed or intended for psychological therapy or medical treatments.
BioZen can display several brain wave bands (Delta, Theta, Alpha, Beta, and Gamma) separately, as well as combinations of several bands using algorithms that may indicate relevant cognitive states, such as meditation and attention. BioZen features a meditation module that represents biometric information with user-selectable graphics that change in response to the user's biometric data.
Biofeedback data is recorded in real time, so users can observe relationships between recorded biophysiological data and their behavior. Users' can create notes to document and categorize their recording session. BioZen automatically generates graphical feedback from the recording sessions to allow users' to monitor their progress over time.
