How It Works

The SIVA Wearable Device is used 24/7 by the patient. The patient wears it on the chest during daytime and keeps it by the bed side during nighttime. This enables continuous cough monitoring over several weeks.

Cough and patient contextual data are transferred to the study investigator or health professional on a daily basis.


At SIVA, we combine the relevant know-how and experience to effectively support pharmaceutical companies in the approval of drugs as well as researchers in answering unsolved questions: clinical and scientific affairs, regulatory affairs, quality management, hardware and software engineering and project management.​

Based on close collaboration with clinical drug development (original partner: Bayer), SIVA currently provides the 'SIVA-MVP research tool' with the following intended use:

The SIVA-MVP is intended for data collection in clinical studies to objectively measure cough of individuals. This data is collected to perform basic or applied clinical research, to establish registry data, or to generate evidence for a cough-reduction drug labeling claim. It is not intended for the diagnosis, prevention, monitoring, prediction, prognosis, treatment or alleviation of a disease.
