PhysioNet's Mission

We seek to promote, catalyze and perform basic-to-bedside research in complex biomedical systems by:

• Making physiologic and clinical data available in open Internet-accessible archives
• Developing innovative open-source software for the exploration and analysis of physiologic data
• Creating a multidisciplinary "laboratory without walls" to facilitate the discovery of basic and translational information in complex physiologic signals

By freely disseminating large and well-characterized collections of data and related software, we aim to lower the barriers for researchers and students whose work requires these essential materials.

Through open challenges, we seek to accelerate progress on specific unsolved problems that can be addressed using available data.

To encourage preservation and reuse of data that may be difficult or expensive to collect, we provide protected data archives for investigators who agree to share their contents in the future.

PhysioNet's Audience

PhysioNet is intended to foster interaction among investigators from many different disciplines. The worldwide community of PhysioNet users includes basic scientists, mathematicians, engineers, clinicians, educators, and students working in biomedical sciences and related technologies.
