BioZen was developed as a pilot project to study the feasibility of using smartphones to receive signals from biosensor devices and display the information in a usable graphic. 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.
BioZen is an innovative mobile app that can be paired with external sensors to provides users with live data covering a range of biophysiological signals, including electroencephalogram (EEG), electromyography (EMG), galvanic skin response (GSR), electrocardiogram (ECG or EKG), respiratory rate, and temperature.
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 psychological information with user-selectable graphics that change in response to the user's biometric data.
Biometric data is recorded in real time, so users can observe relationships between recorded biophysiological data and their thoughts and 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.
Version: 1.8.0 (April 13, 2012) - 11.4MB
