A Novel Type of Micropump Using Solenoid Actuator for Biomedical Applications

In the medical field and in biotechnology, a new type of micropump that can supply micro liquid flow has urgently been demanded. It is our purpose to develop a novel type of micropump that has the characteristics of flexibility, low voltage input, good response and safe for using in human body. In this paper, we propose a new prototype model of a micropump using solenoid actuator as the servo actuator. This paper describes the new structure and the motion mechanism of a micropump using a solenoid actuator and discusses the possibility of the micropump. This micropump consists of two one-way valves, a pump chamber made of elastic tube, and a casing. The overall size of this micropump prototype is 18mm in diameter and 54mm in length. Characteristic of the micropump is measured. The experimental results indicate that the micropump has the satisfactory responses, and the proposed micropump is able to make a micro flow and is suitable for the use in medical applications and in biotechnology.
