Our patient-centric solution in the field of respiratory diseases is unique. It provides:

  • Fully automated and real-time objective 24/7 cough profiles

  • Important patient contextual data

  • A high level of convenience for patients and physicians

The strong performance of the cough detection algorithm is based on a high-quality data pool and our machine learning capabilities.

Longitudinal objectification of cough supports clinical studies and research in generating important patient insights and real-world data.


The SIVA Wearable Device will be used 24/7 by the patient. They will wear it on the chest during daytime and keep it by the bed side during nighttime. Cough and patient contextual data are continuously transferred to the physician / study investigator.

We currently provide the SIVA-MVP research tool with the following intended use:

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.
