Temporary ‘smart tattoo’ could catch skin cancer before it’s visible
A team of Canadian researchers has developed a temporary 'smart tattoo' designed to detect melanomas before they become visible. This innovative technology measures temperature variations on the skin's surface to identify early-stage skin cancer. The goal is to provide a minimally invasive diagnostic tool that could reduce the need for biopsies and improve accuracy in detecting aggressive melanomas.
- ▪The smart tattoo uses microneedles to deposit nanoparticles beneath the skin that function as thermometers.
- ▪Researchers tested the technology on mice and successfully detected micro-melanomas as young as four days old.
- ▪The Skin Cancer Foundation predicts a significant increase in melanoma cases in the US, with 234,680 expected diagnoses in 2026.

Health Temporary ‘smart tattoo’ could catch skin cancer before it’s visible By Reda Wigle Published May 29, 2026, 1:20 p.m. ET See more of our coverage in your search results. Add The New York Post on Google Finally, a new use for temporary tattoos beyond kiddie goodie bags. A team of Canadian researchers says it has developed a temporary “smart tattoo” to spot melanomas before they’re visible — and life-threatening. Published last week in Nature Sensors, the new study evaluated the efficacy of SMEAR-ULM, which measures temperature variations on the skin’s surface to detect skin cancer at its earliest stages. “Our goal is to provide a minimally invasive tool to detect very small, but still aggressive melanomas,” said senior study author Jinyang Liang.
