title = "Quantifying the acoustic field in a microchannel using microswimmers as measurement probes",
abstract = "Rapid and accurate experimental characterization tools can advance development of acoustic microfluidic devices. We previously reported qualitative mapping of acoustic pressure fields using living microswimmers as active probes.1 Here, we apply this method for quantitative measurement of the acoustic energy density as an alternative to conventional particle tracing. Mass density and compressibility of motile Chlamydomonas reinhardtii (CR) algae cells were measured. The acoustic energy density within a straight microchannel driven at the first half-wavelength resonance was then calculated using the balance of swimming and acoustic radiation forces. Measurements are nearly equivalent to those obtained using acoustophoretic migration of passive particles.",
