Edible Lollipop for Independent Pregnancy Detection

A design student developed "Tact," an edible lollipop to help blind and low-vision women independently detect pregnancy, addressing accessibility gaps in healthcare.

Sneha Rao's Tact lollipop reacts to the pregnancy hormone hCG, forming raised bumps detectable by tongue, inspired by blind women's need for private testing.

Current tests are visually read and have inaccessible instructions. Tact offers a private, autonomous solution without digital traces or e-waste.

Tact uses saliva to detect hCG. A positive result shows bumps on both sides of the lollipop; a negative result shows bumps on one side.

Gelatin is the chosen material for its properties and food safety. The next step is integrating hCG-binding DNA aptamers.

Experts note potential challenges in timing and reliability compared to urine tests. Previous tactile prototypes haven't reached the market.

Rao plans clinical testing and regulatory work, aiming to license the technology. Earning trust for an edible diagnostic will be a hurdle.
