How is the biosensor applied to the body?

What is the size of the sharp that introduces the biosensor?

The flexible biosensor is introduced by a u-shaped sharp that is equivalent in diameter to a 23-gauge (0.64 mm) needle. The sharp retracts back into the applicator after application leaving only the filament in the skin.

When applying the biosensor to my arm, do I need to stretch or pinch the skin?

No. Users should only apply the biosensor to the back of their upper arm. Wash the site using a plain soap and water, let it dry completely, and then clean with an alcohol wipe. Allow the site to air dry. Avoid areas with scars, moles, stretch marks, or lumps. Select an area of skin that generally stays flat during normal daily activities (no bending or folding). To prevent discomfort or skin irritation, you should select a different site other than the one most recently used.
