Cor mdx

the voice of the heart

For wearable medical devices to truly serve patients, they must do more than collect data—they must ease anxiety, reduce stigma, and fit comfortably into daily routines. Peerbridge Cor MDx was designed with this empathy in mind, pairing a discreet, user-friendly form with clinical-grade fidelity to capture over 30 cardiac conditions. The result is a device that listens to users and their hearts.

Does it look the same? Good! When tasked with redesigning a wearable heart monitor, their was a strong commitment to maintain the original design of their flagship product. The updated design had to fit the enhanced, next-generation heart monitor components into a sleek, compact package while also solving usability and manufacturing issues of the original design.

The result

Updated material and durometer to accommodate the diverse landscape of users comfortably
A recessed button with haptic feedback made activating the device possible without looking, resulting less frustration and superior clinical accuracy.
While purposely subtle the updated design allowed for crucial increases in space needed to fit the updated internal components.
To accommodate the long wear periods fresh adhesive pads can be swapped onto the device as needed.

6ft, 3ft, & Up Close

Using a multi-distance perspective to evaluate the original design allowed us to identify everything from small manufacturing defects to big usability issues. From their we reviewed each one with the client to create a clear plan for the next iteration.

Designing for Constant Use

When designing a wearable medical device meant for continuous use, a workflow analysis is vital to understand how it fits into every aspect of a user’s life. Sleeping, showering, and exercising create unique movements and situations that must be accounted for. By studying these scenarios, we identified opportunities that would reduce user frustration as well as allow more accurate data collection during constant use.

Material, Durometer, & Shape

To create the most comfortable and durable design, we explored a wide range of materials, durometers, and shapes—evaluating how each combination interacted with the body in motion. Through extensive testing across the full range of human movement, we identified configurations that maintained flexibility, comfort, and resilience, ensuring the device could withstand continuous wear in real-world conditions.
