The cosinuss° monitoring solution was thoroughly tested by the Ludwig-Maximilian University to clarify whether an ear-based sensor technology is actually suitable for reliably and validly recording vital parameters and body temperature in an alpine environment. The prototype of the in-ear sensor, c-med° alpha, was tested in the mountain ambience control room of the Mountain Rescue Center for Safety and Training (BW-ZSA) at -20°C to +20°C and under different wind conditions (+/- 30km/h) with respect to technical validity and suitability in extreme climatic conditions on more than 130 volunteers.
It could be shown that the sensor reliably measures even under unfavorable and changing environmental conditions. In particular, the measured temperature values of the sensor appear to be superior to standard methods, as the sensor creates a kind of “microclimate” in the ear only by textile insulation. It is thus less susceptible to external climatic influences compared to other devices. Based on these promising results, the project was awarded the scientific prize at the 2021 Mountain Rescue Conference (“Wissenschaftlerpreis der Bergrettungstagung 2021”).
