Trust in the experience of Johannes and Greta Kreuzer, founder of degree and parents of three.

Our personal Story

My name is Greta Kreuzer. I am an innovations manager and mother of three. Together with my husband Johannes, who is a PhD medical engineer, we founded cosinuss°. We are developing first-in-class wearable sensors to monitor several relevant vital signs from inside the ear.

The turning point

One day our three year old daughter suffered from a viral infect causing high fever that sud­denly led in to a febrile seizure. Greta sat at her daughter´s bed, taking the temperature every hour. But still she could not see the seizure coming. The reason for the febrile seizure was not the absolute temperature, but the fast rise of it. And that happened between two measurements.

Anne, Lia und Janosch our children were our inspiration for creating degree the wearable in-ear fever thermometer.
The degree thermometer wraps perfectly around a child´s ear and is wearable day and night displaying a steady body temperature measurement inside the degree app.

Our motivation

This incident didn´t let us rest. As we recognized that febrile seizures are quite frequent and not just an incident in our family we put everything on finding a perfect solution for this problem. Parents should be enabled to see the whole temperature curve of their child during fever in order to be able to manage fever more relaxed and without stress. degree° – a very practical helper.

degree° is nothing, without them
