Measuring heart rate without smart watches or contact sensors is possible with a Raspberry Pi. This has been demonstrated by a team of researchers who have created a system capable of monitoring the pulse using a low -cost Wi -Fi chip, even achieving a high clinical precision in just five seconds.
The key is a Raspberry Pi and the project baptized as Pulse-fiwhich makes use of the Wi -Fi channel state information combined with automatic learning algorithms.
The system Analyze how wireless signals are altered as the human body crossesidentifying specific patterns associated with heartbeat. In this way, the heart rate can be estimated in a non -invasive way and without the need to carry any device on.
The tests were carried out with 118 participants and the results surprised, since Pulse-Fi managed to measure the pulse with the same reliability as advanced medical systems, regardless of whether the person was still, walking or moving.
One of the most prominent aspects is its accessibility. Unlike other expensive biomedical equipment, The system achieved the best results using only a raspberry pi 3b.
Although it is an experimental development, if it becomes implemented in a generalized way, it could transform the way health is monitored, eliminating the dependence on watches, bracelets or other medical devices. In addition, its low cost I would do it viable in medical contexts with limited resources.
Researchers clarify that it is not a project to replicate at home, but seeks to open the door to future safe and reliable medical applications that take advantage of wireless technology to offer health monitoring more comfortably and economically.
In short, Wi -Fi not only serves to connect to the Internet, but it could also become a key ally for the preventive medicine of the future.
