  • Printed piezoelectric pressure sensing foil
    Patent number: 9612690
    Abstract: There is provided an sensing device, comprising: a substrate; a sensor ink printed onto the substrate; a conductive polymer ink printed onto the sensor ink; a conductive carbon paste formed on the polymer ink; and a conductive silver ink printed on the conductive carbon paste. There is also provided a sensing device for processing a signal generated by the input device, the sensing device comprising: an operational amplifier to amplify the signal; a filter to filter signal noise from the signal; an adder to apply an offset and attenuation to the signal; a microcontroller comprising an analog to digital converter to convert the signal into a digital output signal.
