Smartphone to measure heart rate.

 heart rate

One of America's Massachusetts Institute of Technology (MIT) has created a smartphone named Biophon. It can also measure the user's heart rate from the other side of the room. When the user stays without any movement, then at home.

From the other end, there are biophones on the other side to identify the vibrations caused by heart rate. However, the movement of the body can not identify hudospanan in shaking caused by movement of other body parts. According to a report, MIT clinic claims that the biophones can detect small vibrations caused by heart attack. This smartphone should not only monitor the health of the user, it will alert the user's relatives at a critical moment starting from breathing exercises if necessary.
