Abstract EN
An analysis of the effect of distance and alignment between two magnetically coupled coils for wireless power transfer in intraocular pressure measurement is presented.
For measurement purposes, a system was fabricated consisting of an external device, which is a Maxwell-Wien bridge circuit variation, in charge of transferring energy to a biomedical implant and reading data from it.
The biomedical implant is an RLC tank circuit, encapsulated by a polyimide coating.
Power transfer was done by magnetic induction coupling method, by placing one of the inductors of the Maxwell-Wien bridge circuit and the inductor of the implant in close proximity.
The Maxwell-Wien bridge circuit was biased with a 10 MHz sinusoidal signal.
The analysis presented in this paper proves that wireless transmission of power for intraocular pressure measurement is feasible with the measurement system proposed.
In order to have a proper inductive coupling link, special care must be taken when placing the two coils in proximity to avoid misalignment between them.
