Abstract
An ultrasound device, including (i) an ultrasound transducer, and (ii) a coupling material in contact with the ultrasound transducer is presented. The coupling material can comprise a solid component and a liquid component, wherein the liquid component is absorbed within the solid component and forms a microscopic liquid layer on a surface of the solid component, through which acoustic energy from the ultrasound transducer can be conducted. The device can be mounted to an external body surface proximate to a portion of the lumen, allowing the device to measure the rate at which a component moves through the lumen. Also provided are methods for making the device and using the device to determine a physiological parameter based on at least the flow rate of a component through the lumen.
