Now, a low-power signal is enough to track the heartbeat of four people at the same time. This development situation has also opened up a new path for the scientific community to explore the application of tracking human body in the search and rescue process, and can also develop a simple signal. To ensure that parents monitor their baby's condition well at night.
With the help of this new technology, parents can monitor the heart rate of a baby living in another room without the need to use any wearable device or special sleeping pad, just use one by MIT (MIT) The latest technology can be developed. This technology mainly uses Wi-Fi signals to track the landing and landing of the human chest.
Researchers at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory are now able to transmit a low-power wireless signal across the wall and monitor the length of time that the signal returns. This change in signal allows the developer to observe the human condition, even the immediate activity of the person's chest.
Researchers at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory monitor human heart rate based on human chest undulation, with an accuracy rate of 99%. This new technology can track four people at the same time.
According to media co-author Dina Katabi, “This has been very difficult to track the immediate heart rate of the human body, but now it can be done with low-cost, usable technology. Important signals from the human body open up new possibilities."
Recently, researchers at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Lab have been perfecting their Wi-Fi tracking technology, and have also used wireless signals for 3D tracking.
In addition to tracking the baby's heart rate, this new technology system can be applied to the search and rescue process and can also be used to track the user's own health data. Researchers at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory are also considering further expanding the technology system so that it can be used to track people's emotions, etc., of course, by connecting people's heart rate and breathing conditions.
