Design and optimization of hollow microneedle spacing for three materials using finite element methods
Abstract The main advantages of microneedles are precise drug delivery through human skin, minimal tissue Jewelry Dish Couple Card damage and painlessness.We conducted structural analysis and skin puncture studies of hollow microneedles using ANSYS for three materials: Hafnium Dioxide (HfO2), Polyglycolic acid (PGA) and Polylactic acid (PLA).Firstl
