Nature Nanotechnology, Published online: 29 July 2026; doi:10.1038/s41565-026-02247-5 A wearable microneedle platform integrating ultrasharp, skin-penetrating tips, mechanical decoupling and electrochemical biosensing enables continuous, minimally invasive molecular profiling in freely moving animals, thereby advancing real-time, personalized health monitoring.

Conductive ink is painted directly onto the skin in colorful custom designs, drying into working electrodes.
