Abstract: A method includes applying a high frequency signal to an electromechanical actuator and measuring a first response of the electromechanical actuator to the high frequency signal, estimating electrical parameters of the electromechanical actuator based on the first response, applying a low frequency broadband signal to the electromechanical actuator and measuring a second response of the electromechanical actuator to the low frequency broadband signal, and estimating mechanical parameters of the electromechanical actuator based on the second response and the estimated electrical parameters.

Abstract: A method of recording measurement data for characterizing a response of a given type of device to an applied force, the given type defining devices of that type as comprising a defined arrangement of a surface and N force sensors of the device concerned, where N≥1, each force sensor configured to output a sensor signal, wherein in the defined arrangement the N force sensors are operatively coupled to a defined input region of the surface so as to sense a force applied to that input region, the method comprising: for a specimen device of the given type, performing at least one measurement procedure, each measurement procedure comprising at least one measurement operation, each measurement operation comprising applying a defined force at a corresponding location on the input region of the device concerned and recording measurement data for that device and location based on the sensor signals of the N force sensors of that device. Also disclosed are a related computer-implemented method of generating a characterization definition for devices of the given type, a computer-implemented method of generating a configuration definition for devices of the given type for a given use case defined by a use-case definition, a method of configuring a candidate device of the given type for the given use case, and a method of assessing or calibrating a candidate device of the given type.
