Design, Simulation, and Prototyping of an Impulse Turbine for Biomedical Applications


Keywords: , , ,

An impulse bio-turbine with circular inlet/outlet area is presented. The system was designed using a scaled impulse macro turbine model, which was modified in size and shape to facilitate transformative integration in implantable biomedical devices and physiological circulatory systems. In addition, the design simplicity reduces cost and makes it very suitable for developing MEMS technology or prototyping machine systems. Simulations were performed to examine the structure and the flow behavior inside of the turbine and to determine optimum conditions for turbine rotation. The simulation was developed in two different moments. The first moment was using a rotor fixed and in the second moment the rotor has free rotation. The turbine prototype laboratory tests and some materials and process for bio compatibility are presented. It is hypothesized that when all faces and borders of the design are covered with a biocompatible materal, such as Silicon Carbide (SiC), this design will be most beneficial for in-vitro and in-vivo systems, such as biomedical systems, artificial organs, valves, sensors, micro and nano motors, and micro energy generators. This bio-impulse turbine has the potential of transforming parts of systems that have lifetime limitations and compatibility problems.
