Cnoga was invited by NATO to assess the implementation of new technologies for the military forces of NATO. Matrix monitor (MTX) was chosen due to the unique capability to measure 15 bio-parameter non-invasively and transfer them in real-time for the needed analyses. A subgroup in NATO called EOD-COE (Explosive ordinance disposal center of excellence), asked to assess new technology. The new technology, Exoskeleton, is a passive skeleton (i.e. non-motorized) and its objective is to provide relief to the soldier during certain actions and movements. More specifically, NATO wanted to examine if the device would make it easier for soldiers to wear an explosive suit that weighs 47 kg.
Until now the way to evaluate such technologies was by using questionnaires and old sphygmomanometry technology after the activity.
MTX uniqueness enabled to evaluate objectively the ability of different prototypes of exoskeletons to relieve some of the load on soldiers’ body during different tasks. By measuring different parameters simultaneously in real-time, such as blood pressure, pulse, blood gasses, and cardiac output, that are affected by anaerobic exercise. All bio-parameters were measured during different tasks like running, carrying weight with steps, etc. and transferred in real-time by “Singular” app for further analysis. Recovery time was measured with and without the Exoskeleton. The difference between the measurements (HR, CO, BP, pH, PO2, PCo2) was taken during the tasks and at the initial resting time. The desired outcome was that using the Exoskeleton, we could be able to see that the soldier is straining less and that his recovery time after task completion would be shorter, thus reducing the difference between measurements during the task and during rest in comparison to measurements without the use of the Exoskeleton
It was clear from the data that some of the exoskeletons added significantly higher strain on the soldiers, for example, a soldier without the Exoskeleton started at 4L/min cardiac output at rest and increased to 8-9 L/min during the task, whereas the same soldier wearing the Exoskeleton started at 6-7 L/min cardiac output and increased to 18-20 L/min, showing obvious differences. Those results were compared to filled questionnaires that presented the same conclusions.
