Abstract

<p>To develop a simple and accurate measurement technique of intramuscular fat, we present a new sensing method based on the change in the electrical impedance by muscle stretch. The system obtains the electrical gain characteristics of the muscle tissue for various stretch conditions, and identifies the parameters by fitting the transfer function of the equivalent circuit to the obtained data. Then, the amount of intramuscular fat is estimated by the multiple regression model using the parameters. For the feasibility evaluation, we investigated the estimation error by using a phantom that mimics the electromechanical properties of muscle and fat. As a result, we found that the proposed system is capable of estimating the fat amount with 2.7 % error. Because the estimation error of the sensing method without muscle stretch conditions was 5.6 %, the use of muscle stretch was found to be effective for reducing the estimation error.</p>
