Abstract
Recently, ultrasound has been used for power transfer and backward data transmission from implantable medical devices. Backward data communication is typically based on the amplitude modulation of the backscattered signal with changing electrical load of the implant. Contrary to its importance, the sensitivity of the backscattered voltage with reference to the electrical load has not been quantitatively determined yet. This work presents the results of transient simulations and shows the increasing trend in echo voltage with the increasing load resistance. Additionally, simulation studies indicate a decreasing sensitivity of echo voltage to load resistance with increasing backing impedance of the implant.
