cosinuss° in der Wissenschaft

Unser Ziel ist es, Gesundheitsdienstleistern die Instrumente an die Hand zu geben, die sie benötigen, um ihren Patient:innen die bestmögliche Versorgung zu bieten. Daher entwickeln und validieren wir unsere Sensortechnologie kontinuierlich weiter. Diese Entwicklung zeigt sich in zahlreichen Studien und Projekten mit verschiedenen Anwendungsszenarien. Es wurden sowohl interne Studien, externe Kooperationen mit renommierten Universitäten, Kliniken und anderen Unternehmen als auch komplett von uns unabhängige Studien mit unserer Sensortechnologie durchgeführt. Die nachfolgende ausgewählte Sammlung gibt einen Einblick in die Ergebnisse und Erkenntnisse aus den bisherigen Forschungsaktivitäten.
