Acoustic Processing of Fluidic Samples for Planetary Exploration

The search for life on other planetary bodies is driven by our quest to determine if Earth unique with respect harboring life. In order answer this question, instrumentation suitable sensitivity required measure biosignatures. addition accurate measurements in-situ instruments, specialized sample acquisition and handling hardware maximize the scientific information obtained from an acquired sample. This paper discusses a class of compact processing using solid-state mechanisms that use acoustic waves process samples prior delivery instrument. Some processes can be used aid in preparation liquid liquid/solid mixtures include: mixing, milling, cavitating, lysing, heating, streaming, stirring, lofting, concentrating, segregating, filtering. We will review these show how they are generated electromechanical systems. processing, transduction systems could also acoustics interrogate physical properties such as state sample, velocity, its attenuation. generate sensing capabilities at frequencies, mechanism produce stress electrical signals vice versa . One commonly technique piezoelectric transducers linearly proportional voltage across transducer transducer’s face. A variety modes available excite including thickness, transverse, radial, shear extensional, build composite resonance structures ultrasonic horns, tuning forks, bimorph, unimorph benders increase discuss model interactions chamber illustrate network models accomplish modeling. demonstrate up Mason’s equivalent circuit layers design. Finally, ability, we few have developed like Mars ocean worlds Enceladus Europa.
