Abstract

Portable health management devices such as mobile phones, based on the biofeedback principle, are becoming increasingly attractive for scientists and individuals who strive to achieve a healthier lifestyle. Portable health management devices such as mobile phones equipped with sensors to provide biofeedback are becoming increasinglyattractive to scientists and other individuals who strive to achieve a healthier lifestyle. Under the auspices of the OPTIMI project we have developed and tested a new ECG biofeedback sensor. This sensor monitors heart rate variability as an indication of a participant's level of stress and relaxation. In the study, participants practiced slow, conscious, meditative breathing while observing biofeedback in the form of visual stimulation from the sensor. The training was carried out in healthy volunteers, who as a result of the biofeedback exercises could improve their coping strategies.
