Scientists turn toothpaste into edible transistors for smart health tracking | Copper phthalocyanine, known for its teeth-whitening properties, can also be used as a semiconductor material.
The researchers integrated small amounts of copper phthalocyanine into an edible circuit, creating a transistor that operates on a low voltage.
“With the amount of copper phthalocyanine we ingest daily, we could theoretically manufacture approximately 10,000 edible transistors,” said Elena Feltri, the lead author and a doctoral student at the institute. The researchers integrated small amounts of copper phthalocyanine into an edible circuit, creating a transistor that operates on a low voltage. As per the press release, these edible transistors could be used in smart pills to monitor vital signs, detect diseases early, deliver targeted treatments, and even control food quality.
