This Lollipop Could Help Blind Women Independently Detect Pregnancy

Sneha Rao, a 27-year-old Carnegie Mellon design student, has developed Tact, an edible lollipop-based pregnancy test that allows blind and low-vision women to detect pregnancy independently by feeling raised bumps triggered by the pregnancy hormone hCG—addressing a systemic gap in accessible health care design that has forced blind women to depend on others to read visual pregnancy test results.

Tact is a prototype in development. Clinical validation and regulatory approval would be required before market availability.
