What this trial studies

This study aims to evaluate the effectiveness of an optical blood pressure monitoring device by collecting raw optical data from participants using the Aktiia G2C system. A minimum of 85 participants will be involved in a single visit lasting about one hour, during which various reference systems will be used for comparison. The study will include individuals with diverse phenotypes to assess the device's performance across different populations.
