Investigation and modeling on electroformed micro electrolysis pump using regression analysis

Abstract

Abstract The purpose of this study is to investigate using electroforming process for manufacturing an electrolysis micro pump. Also characterization and modelling of prepared micro pump was explored. For this reason, firstly a setup for mandrel shaping using abrasive assisted chemical machining was built. Secondly, another experimental setup for copper electroforming process using copper sulfate bath was made. After manufacturing micro pump's body using electroforming process, it assembled and characterized. For characterization, mean flow rate for discharging a fix volume of liquid, 0.3 milliliters of water, by applying 2 to 10 Volts of electrical voltage in five steps was measured. The mean flow rate measured between 0.09 to 0.56 (mL/min) at different applied electrical voltage. Furthermore, regression model was developed that described the relation between applied voltage and pump's mean flow rate as linear. Confirmation tests were conducted for verification of proposed regression model too.
