Stiff consideration of a micro painless needle with polygon section
A micro painless needle is copying the mouth of a female mosquito, and possess inside diameter 25 [m m] and out diameter 50 [m m] The material considers biocompatibility and adopts Ti. I compose using the sputtering technique which is one by a film creation method. because creation is difficult for a micro painless needle by mechanical processing of existence. But a stiff decline with size decrease of a needle can be named as a problem. It's previously announced, for, the bend test which saves and comes near to micromanipulator and the Young's modulus using general purpose finite element analysis soft ANSYS Workbench which confirm the stiffness of a created needle are calculated, and since it was checked, but putting linearity in the load around ,250 [m m] experimental value and the difference have occurred to experimental value and analytic value. The price to which more micromanipulator fell compared with the general Young's modulus by a decline of the measurement accuracy of the reaction force in experimental value is calculated, but it's the current state. So I have measurement accuracy improvement of experimental value for my object in a needle with sections like a polygon by this report, and it's low load and a smaller step size bend test is performed and the Young's modulus by general purpose finite element analysis soft ANSYS Workbench is calculated.
