LifeSensor, life detection and monitoring system
This technology allows to detect the movements of a person and to measure their respiratory rate when it is still
Nowadays where immediacy dominates everything, we can still find limitations in some of the technologies used by professionals who take care for the well-being and health of people. Whether indoors or in larger areas, it is necessary to develop both technologically feasible and effective alternative solutions for urgent and fast needs of professionals.
Gradiant, aware of the possibilities open to the wireless measurement of vital parameters such as respiratory or cardiac frequency, has developed LifeSensor, a remote life monitoring system that allows the detection of a person’s movements and their respiratory rate when it is still.
This system, the result of almost four years of work, “allows to monitor the respiratory rhythm and movement of a person in a non-invasive way, optimizing the surveillance from a radar system that detects the existence or absence of breathing, It is possible to prevent and prevent the deaths of people indoors” explains Jorge Munir, Director of Advanced Communications at Gradiant.
Radiofrequency technology to save lives
LifeSensor is a vital monitoring system capable of detecting a person’s movements at a distance, as well as measuring their respiratory rate when the person is quiet.
This system is based on radiofrequency technology and works in a similar way to what a radar does, meaning “we have a signal transmitter-receiver that, once processed, offers relevant information about the individual: if the person is quiet or in motion, his/her respiratory rate, etc.”, says LifeSensor combines enough penetration and range to allow monitoring with a single device that also performs a very solid signal processing against possible interference, always guaranteeing the privacy and anonymity of the people. The UWB technology (high-bandwidth radar technology) the system incorporates has a detection range up to six meters (although it is already working to extend this range up to ten), and is able to operate through everything kind of materials such as clothing or sheets, wood, stone or cement.
Increasingly, security forces and rescue teams rely on technology to improve and expedite the search in those situations where people’s lives depend on the urgency and precision with which they act. For this reason, the use of this technology is also being explored for searching living people in search and rescue scenarios using Unmanned Aircraft Systems or UAS.
Future technology for any sector
“The ‘magic’ of LifeSensor lies in the information signal processing provided by the hardware platform system has”, notes González, as “it is the basis for being able to transform the radio frequency signal used by the system in useful information about the movement and breathing rate of the person”. In addition, LifeSensor incorporates antennas, specifically designed, to reduce the interferences and improve the performance of the whole system.
Although there are remarkable differences between the challenges in each use case, the challenge of any new technology solution is focused on the need to lower the costs of the hardware technology needed to support the system. The UWB technology on which LifeSensor is based is currently expanding, mainly due to the emergence of low cost hardware platforms. For this reason, all the previously mentioned applications add the ability to provide precise distance and location measurements, detection of buried objects, domotics, etc., making it a cross-cutting and promising technology.
