Carlos Ribeiro, a researcher from IT in Aveiro, has developed a wireless technology called REVOsdr that allows real-time communication for future 5G systems. With applications that can range from outer space exploration to home appliances and entertainment, this 100% Portuguese technology promises to have a great impact not just in the big companies but also in our homes and daily lives. The project that was already awarded by the Carnegie Mellon University gave rise to the start-up TWEVO (Tactile Wireless Evolution) Lda.
The possibility of using this technology in space exploration might be TWEvo´most exceptional step. Carlos Ribeiro reveals that "one of the most extraordinary meetings I've had in the US was with the CEO of Astrobotics, one of the few North American companies that produces rovers used in the exploration of other planets”. “I couldn´t believe that the company which is creating autonomous vehicles to be used in the colonization of Mars was interested in our technology, "concludes the IT researcher.
However, TWEvo´s mostly focused on drones, more specifically, in trying to restrict the delays that occur in the transmission of data due to the video compression. Therefore, TWEvo's technology is the appropriate solution to achieve greater speed and precision, which will allow high-precision work.
Researchers from IT in Aveiro and the Instituto de Engenharia Electrónica e Telemática of Aveiro (IEETA) have developed a radar that is able to register the human respiratory rate from a distance, without the need of any mechanical contact. The prototype is called Bio-Radar.
But how does the Bio-Radar work? By determining distances through the reflection of radio signals, the Bio-Radar can detect small movements in the chest that are the result of inspiration and expiration and, from there, it records the respiratory rhythm.
Already effective in registering the respiratory rate, the researchers´ next goal for Bio-Radar is that it´ll also be capable of measuring the heart rate. According to the researchers´ explanation, "The periods of systole and diastole of the heart create small movements in the chest that can be measured by the system and, from there, registering the cardiac rhythm”.
Given its non-invasive characteristics, there can be many applications to the Bio-Radar. “It can be used in hospital settings for evaluating a patients´ health state without the use of contact” and even “in cars to measure the level of stress or relaxation of a driver or even to detect if the driver is close to falling asleep at the wheel”, said the research team. Additionally, since it uses radio waves, the equipment can be placed behind everyday objects without impairing its effectiveness to obtain bio signals.
Effective, fast and convenient, for both patients and physicians, the Bio-Radar promises to turn every other method currently used for measuring the respiratory rate into something of the past.
