microneedle
Minuscule skin piercer
A microneedle is a tiny needle, typically less than a millimeter long, used to penetrate the outer layer of skin without reaching pain receptors.
Microneedles appear in patches for drug delivery, skincare treatments, and vaccinations: The microneedle patch delivers insulin painlessly.
They can also sample fluid for glucose monitoring.
