The overall goal of goal of this project is to study the wind speed on Mars using sonic anemometry. Micromachined ultrasound transducers fabricated at Tufts University have been shown to work in Earth’s atmosphere. In this thesis work, an effort has been made to understand how these devices would perform if placed in a Martian environment. A special emphasis is placed on how pressure influences ... read moretheir undamped natural frequency and their quality factor. The validity of the modeling that has previously been used to design these transducers is also discussed. Finally, new fabrication techniques that were used to build a new sensor with a thinner structural membrane are presented.read less
