KidneyX Prize Winners Rethink Dialysis

Artificial kidneys and a wearable that prevents blood clots were among the winning designs

In the 1960s, a pacemaker was the size of a microwave and a dialysis machine was the size of a refrigerator. Today, a pacemaker is the size of a vitamin and a dialysis machine is, well, the size of a refrigerator. They do have nice LED displays though.

“Kidney disease is underserved,” says Shuvo Roy, a bioengineer at the University of California, San Francisco. Although failed kidneys kill more people each year than breast or prostate cancer, “the field has not seen much innovation in the last 50 years,” says Roy.

The U.S. Department of Health and Human Services and the American Society of Nephrology want to change that. The organizations have teamed up to bring money and attention to the disease with the KidneyX: Redesign Dialysis competition. Started in 2018, the competition challenges innovators in any field to propose tools and technologies that could enable the design of new artificial kidney devices.
