Integrated sensor for medical applications
First Claim
1. A sensing assemblage for measuring a parameter of the muscular-skeletal system comprising:
- an ultrasound waveguide with two ends; and
a first transducer and second transducer each placed at one of the ends of the ultrasound waveguide where the first transducer and second transducer operate together to measure changes in the propagation characteristics of ultrasound waves within the waveguide and where the sensing assemblage is configured to couple to the muscular-skeletal system;
wherein a series and parallel resonance of the first transducer does not overlap a series and parallel resonance of the second transducer.

Abstract
A sensing assemblage (1) for capturing a transit time, phase, or frequency of energy waves propagating through a medium is disclosed to measure a parameter of the muscular-skeletal system. The sensing assemblage (1) comprises a transducer (2) and a waveguide (3). The transducer (2) is coupled to the waveguide (3) at a first location. A second transducer (11) can be coupled to the waveguide (3) at a second location. An interface material that is transmissive to acoustic energy waves can be placed between transducers (402, 404) and a waveguide (414) to improve transfer. The interface material (408, 410) can affix the transducers (402, 404) to the waveguide (414). Alternatively, a reflecting feature (5) can be placed at a second location of the waveguide (3) to reflect acoustic waves back to the transducer (2) where transducer (2) emits energy waves into the medium and detects propagated energy waves.
