In recent years, smartphones have learned to closely monitor the physical activity of its owner, made by counting the number of steps and keeping their data on heart rate. Handheld devices such as smart bracelets are able to gather a lot of data without stopping. All this can be useful not only for those who lead an active lifestyle, but also, for example, people with heart disease.
Nevertheless, bracelets require continuous wear. Researchers at the Massachusetts Institute of Technology are working on a project called BioPhone, lets you use the accelerometer and gyroscope smartphone as a biomarker of body movements.
Researchers suggest catching vibration caused by, for example, heart rate. As noted, in comparison with the heart rate monitor, approved by FDA (Office of FDA Food and Drug Administration in the US), BioPhone mistaken by an average of one beat per minute, respiratory rate is measured with an accuracy of 0.25 inhale-exhale cycle.
This, however, is probably talking about the tests in conditions far from reality. The developers at MIT acknowledged that BioPhone should improve the accuracy: BioPhone algorithms can deal with the processing of motions and external interference, but the location of smartphone is still important for the correctness of the measurements.
