Certification

Quality and Safety of cosinuss° products

The development, manufacturing and distribution of medical devices requires a specific company structure that enables the quality and safety of the product to be met in accordance with the regulatory requirements for medical products. The specific requirements for a Quality Management System are specified by the European Directives for Medical Devices (MDD, MDR) through the harmonized standard EN ISO 13485:2016.

For this purpose, cosinuss° has defined appropriate internal processes and established an ISO 13485-compliant Quality Management System covering design and development as well as production and distribution of monitoring devices of vital physiological parameters. The Quality Management System is audited regularly by the accredited Notified Body TÜV Süd to proof its functionality according to the harmonized standard EN ISO 13485:2016. The current certificate can be downloaded here: cosinuss-certificate-EN ISO 13485:2016.pdf

Moreover, the ISO certification is also the basis for CE approval for medical products of class IIa. cosinuss° is currently undergoing the conformity assessment procedure according to MDD Annex II without (4).

History

Technology, Research and Development

Greta and Johannes founded cosinuss° in September 2011 based on the findings of the PhD work of Johannes, which focused on developing the first wearable medical devices for home use.

Starting in the field of research and enabling technology, cosinuss° provided in the very beginnings research institutions and companies who care about the health of their customers, with enabling technology.

The first consumer product, cosinuss° One, was introduced to the market in mid 2016. The °One is a performance tracker for professional athletes to balance health and performance, health being the critical driver of performance. Since then, it found its way into professional areas of triathlon, Formula 1 racing, sailing, motorsports, fire fighters and swimming.

Greta Kreuzer, Johannes Kreuzer - cosinuss° Gründer

In 2017, cosinuss° started a successful Kickstarter campaign to launch its second consumer product, degree°. degree° is a smart digital fever assistant that continuously measures core body temperature of the child and helps parents making decisions based on it.

Further solutions and enabling technology is in development/available for:

Remote patient monitoring
COPD monitoring
Home Health solutions
mHealth solutions
In-clinic patient monitoring

Our Vision

Empowering people to manage their health and fitness at home.

Providing enabling technology for companies who share our vision and developing own complete solutions for selected health issues.

Our DNA

Enabling Individual mHealth Solutions

cosinuss° builds high precision in-ear sensors that continuously capture relevant vital signs in every day life. Because individual vital signs data is the essential component to create individual health insights. Only accurate data can be the basis of that.
