FujItsu has unveiled a smartphone that allows a user's pulse to be taken just by pointing the camera at his or her face for as little as five seconds, without the need to wear any special devices.
The Japanese technology firm plans to put the invention into practical use within a year, enabling people to track their health at home and collect data for analysis, according to a press release Monday. The technology will be built into smartphones, tablets and PCs.
The device detects the variations in the brightness of a person's face caused by the flow of blood. Specifically it monitors the hemoglobin found in blood, which absorbs green light.
"This technology has a wide range of potential uses, including health monitoring and maintenance as well as security applications," said the statement.
There has been increasing awareness about the need to maintain the health of employees and senior citizens, raising the demand for new, more convenient ways for individuals to monitor and manage their health, anytime and anywhere, added Fujitsu.
