Experimental characterization, modeling and compensation of hysteresis in force sensing resistors

Abstract: Force Sensing Resistors (FSRs) exhibit considerable amounts of hysteresis and repeatability error inhibiting their usage in applications that require high-accurate force readings. This paper presents the hysteresis characterization and modeling of the Tekscan A201-1 FSR employing the Preisach Operator (PO) function. In order to compensate for hysteresis during sensor operation, the inverse PO was numerically found on the basis of the Closest Match Algorithm (CMA). A test bench, capable of handling sixteen sens… Show more

“…Several sensor references were analyzed such as the Tekscan A-201, the Ohmite FSR03CE and the Interlink FSR400. These sensors were selected based on our own experience and after having made a small state of the art of the existing sensors [ 29 , 30 ]. Important criteria were reliability through hysteresis (change in behavior during use), sensitivity (minimum force required to read data), force sensitive area and stability (defined here as “at rest” resistance).…”
