Abstract
In this research, heat-acupuncture needle was coated with $Al_2O_3$ by applying a plasma spray coating method to prevent a skin burn. $Al_2O_3$, which is one of the representative bioceramics, does not have an influence on the chemical change in the body system. The ceramic coating thickness was about $100{\mu}m$. The experiments of heat conduction were performed for uncoated needle and coated needle. The results showed that the surface temperature of needle decreased as the needle was coated with $Al_2O_3$. The surface temperature of uncoated needle was about $48^{\circ}C$, while that of needle coated with $Al_2O_3$ was about $39^{\circ}C$.
