On the optimal electric loads for ultrasound energy receivers

In this paper, we experimentally verify the difference between the zero reflection condition and the power maximization approach for the optimal electric loads. First, we predict those optimal loads with the KLM model for a 1-3 composite transducer that we use as a receiver, and we then perform expe...

Summary:In this paper, we experimentally verify the difference between the zero reflection condition and the power maximization approach for the optimal electric loads. First, we predict those optimal loads with the KLM model for a 1-3 composite transducer that we use as a receiver, and we then perform experiments in deionized water with different ohmic loads attached to it. The measurements confirm that the electric loads that achieve the highest efficiency of the receiver are not equal to the loads that minimize the reflections.
