Needle Coatings to Relieve Penetration and Drag Forces of Needles

A study comparing penetration forces of uncoated and coated needles was performed to analyze and compare the efficacy of specific NuSil needle coating materials in lowering the force required to penetrate and pass through a substrate. Testing was performed on a TA.XT.plus Texture Analyzer with a 5-kg load cell. Needles coated with MED-4162 proved to have the largest decrease in penetration and drag forces.
