A computer manufacturer based out of California is developing heartbeat sensors to unlock phones and other gadgets. While at this time the manufacturer's sensors are only being installed into phones to monitor heart rates (such as those of cardiac patients), the company's patent expresses that such a development could be extrapolated to be used for user identification and authentication.

Heartbeat sensors to unlock phones stands to be a huge development in the tech world--the user's pulse could be measured through the touchscreen on certain gadgets, which could allow for the detection of unique heartbeat patterns and thus the ability to distinguish users.
