Abstract:V diplomskem delu obravnavamo vpliv vibracijske naprave na delovanje mikrofluidnih motorčkov. Mehanizem vibracijske naprave je mehanski ojačevalnik, ki ojača pomike piezoelektričnih aktuatorjev. Pri tem smo testirali vpliv oblike in lastnosti materiala mehanizma vibracijske naprave na hitrost vrtenja vode v lončku in pa vpliv sklopljenosti ter pritrditve mehanizmov na amplitudo pomikov, ki jih generira mehanizem vibracijske naprave. Prav tako smo raziskali popačenje pomikov zaradi ojačenj pomikov ob resonančnih frekvencah mehanizmov vibracijske naprave in pa zaradi popačenja krmilnega signala. Nadalje je predstavljen razvoj mikrofluidnega motorčka na osnovi lončka z osjo. Pri tem smo izdelali rotor motorčka iz sploščene četrtine kroglice stiropora, os iz bakrene žičke premera 200 μm ter ležaj iz optičnega vlakna notranjega premera 240 μm. Pri tem smo uspeli krmiliti hitrost vrtenja mikrofluidnega motorja s spreminjanjem amplitude napetosti krmilnega signala. Prav tako smo uspeli doseči spremembo smeri vrtenja mikrofluidnega motorja, vendar z majhno ponovljivostjo.

Title:The Testing of Vibration Devices on a Microfluidic Motor
Abstract:In the diploma thesis, we deal with the influence of the vibration device on the microfluidic motor. The mechanism of a vibration device is a mechanical amplifier that reinforces the movements of piezoelectric actuators. We tested the influence of the shape and material of the vibration device on the rotation speed of the water in a pot and the effect of the coupling and the attachment of the mechanisms on the amplitude of the movements generated by the mechanism of the vibration device. Furthermore, we investigated the distortion of displacements that were the result of the resonance frequencies of the mechanisms of the vibration device and the distortion of the control signal. The development of a microfluidic motor in a pot with an axis is also presented. For this purpose, we constructed a rotor from a quarter of a flattened Styrofoam ball, an axis made of a copper wire with a diameter of 200 μm, and a bearing made of an optical fibre with an inner diameter of 240 μm. In doing so, we managed to control the rotational speed of the microfluidic motor by changing the amplitude of the voltage of the control signal. We also succeeded in changing the direction of rotation of the microfluidic motor, but with a low repeatability.
