NONLINEAR MODELLING IN BIOMEDICAL APPLICATIONS USING ANNS

Vančo Litovski, Miona Andrejević Stošović

Abstract

During the design of many biomedical prostheses based on electrical and electronic fundamental actions, simulation is indispensable. It comprises, however, necessity for adequate models to be used. Main difficulties related to the modelling of such devices is their nonlinearity and dynamic behavior. Here we report application of recurrent artificial neural network for modelling of a nonlinear two-terminal circuit equivalent to a specific implantable hearing device. The method is general in the sense that any nonlinear dynamic two-terminal device or circuit may be modelled in the same way. The model generated was successfully used for simulation and optimization of a driver (operational amplifier) - transducer ensemble. That confirms our claim that optimization in the electrical domain should take place in order to achieve best performance of the hearing aid. It is to be contrasted to the optical methods based on surgery frequently used.
