Sensitivity of a system

  1. Jun 25, 2009 #1
    Hello!

    I have the following problem

    My Physical System
    I have a sensor which changes resistance on application of force.

    Experiments performed

    In order to characterize the output of the sensor, I have done some experiments. In the one of interest here, I applied different forces and took 4 readings at each force step. Total force steps are 5.

    My final graph is force on X-axis and magnitude of resistance on Y-Axis.

    Problem
    I want to analyze sensitivity of the sensor.

    What I have tried

    I tried to caluclute the sensitivity of the sensor using the acquired data in GraphPad. But there seem to be some error. i want to calculate it using manual mathematics now.

    Kindly guide me how to do it. An example will be great.

    Thanks for your time
