Some researchers at the University of Buffalo have created a way for a computer to use your heart as a form of biometric identification using a type of radar generally used for far away objects. They have successfully created the hardware and software using a specific heart’s movement, and its size and shape to unlock a computer or other device. After originally unlocking the device, the heart is continually monitored, so if someone else takes the first person’s place, it locks.
One of the amazing things about this technology is that it doesn't work on dead people. Now, you may be thinking: "Will this hurt my heart?" The answer is no, the signal strength is 8 milliwatts, less than 0.2% than that of a Wi-Fi signal, which contains no health threat.
