Abstract


  • We present our experimental investigation into

    mechanochemoelectrical behavior of tri-layer polypyrrole (PPy)

    -type conducting polymer sensors. One end of the polymer strip

    is clamped and the otherfree endis excited through a

    mechanical lever system, which provides sinusoidal displacement

    inputs. The voltage generated and current passing between the

    two outer PPy layers as a result of the displacement input is

    measured to model the output/input behaviour of the sensors

    through their experimental current/displacement and

    voltage/displacement frequency responses. We specifically

    targeted the low frequency behaviour of the sensor as it is a

    relatively slow system. Experimental transfer function models are

    generated for three sensors with the dimensions of

    (7.5mm×1mm×0.17 mm), (10mm×1mm×0.17 mm), and (12.5

    mm×1mm×0.17 mm). These models are for use in understanding

    the dynamic behaviour and sensing ability of the polymers as

    mechanical sensors. The effect of the active sensor length on the

    voltage and current outputs are investigated that the shorter is

    the sensor length, the higher are the voltage output and the

    current passed. Also, their current and voltage responses under

    an impulse stimulus (i.e. displacement) are experimentally

    measured to show their dynamic sensing response.
