Technology, Research and Development

The patented technology that cosinuss° uses in its in-ear sensors was invented by the founder, Johannes.  Johannes now has 10 years of R&D experience in the field of mobile vital signs sensors, which began with a research project that aimed at enabling elderly people to stay at home instead of having to live in a care center by enabling them to monitor their health at home.

Our Vision

A doctor in a pocket

Providing families a tool to enable them to manage their health more confidently. Regardless if they do it alone or in partnership with their physician.

Our Team

Getting things done

We are a team of highly motivated electrical engineers, data scientist, designers and marketers who deeply believe in the great potential of the earconnectTM technology of cosinuss° and who are determined to bring this technology into the families.
