Description
Summary:The use of biomedical implants has been on the rise over the recent past years and this use is expected to increase exponentially over the comings years. Such devices are becoming the most feasible interface to monitor the betrothed parameters. Biomedical implants usually require a low input voltage which is provided making use of inductive coupling. Inductive coupling not only solves the powering issue but also helps to collect the data through non-invasive means. Power transfer efficiency of an inductive link system depends upon factors like mutual coupling, separation between the coils and most importantly the shape of the input voltage. The power transferred or signal received as a result of coil separation under optimum size conditions are reported in contemporary works. This paper comes is testing the effect of different shaped input voltages on the performance of inductive coupling system in terms of power transfer efficiency. Circuits have been tested for three different types of input waveforms of sine, square and ramp. Comparison of plots shows that the shape of input plays a major role on the entire performance of inductive coupling system.
