Abstract

The contribution deals with evaluation of uncertainties in the process of calibration of multicomponent sensors with special aim to force matrix sensor arrays. Matrix sensors are designed for simultaneous measurement of acting forces. It is used in applications in which sensing of varying forces acting in an area is needed (e.g. in robotics, telemanipulating devices, medical applications). Model for calibration of matrix sensor arrays and the methodology for uncertainties and covariances calculation is submitted. The base is regress polynomial model of calibration. The result is estimation of model parameters and covariance matrix of those estimators. Considered are all uncertainties and covariances, resulting from measuring standard device, transmission of values from measuring standard to sensor, repeating of values by calibrating sensor. The most important characteristics of current stateof- art in this field is absence of unique procedures used for objective matrix sensor arrays evaluation and testing.
