Medical Aerosol Flow Rate Estimation for Smart Inhaler Development

The study focuses on the implementation of flow rate sensing and measurement in smart inhalers for the effective management of respiratory diseases. It highlights the importance of adhering to proper inhalation techniques and maintaining consistency for managing respiratory conditions. Methods and relevant commercial and prototype research-type devices for sensing and measuring inhalation flow rate in smart inhalers are evaluated and compared. The findings show that the utilisation of acoustic analysis combined with air-pressure sensing is a promising approach to detect and assess the inhaling action, ultimately allowing for improvement in treatment outcomes and quality of life for patients with respiratory diseases.
