Ambient Pressure Sensitivity of Subharmonic Vibrating Single Microbubbles
The dependency of subharmonic oscillation amplitude to changes in ambient pressure can be explained by a shift in the resonance frequency of the bubble as a function of ambient pressure. The subharmonic response increases with ambient pressure when the resonance frequency shifts toward half the driving frequency and decreases when the resonance frequency shifts away from half the driving frequency. These findings help to understand non-invasive pressure sensing through subharmonic ultrasound imaging.
