Development and Application of a Pencil-on-Paper Strain Sensor for Pressure Measurement
Nur Shahira Shahripul Azeman | Mohd Norzaidi Mat Nawi 
Abstract: The development and application of a strain sensor using pencil-on-paper is presented in this paper. The use of pencil which contains of graphite create a simple sensing technique that can be used to measure the pressure force. When the pressure force is applied, the beam will deflect and give a change in resistance. A comparison was made using two different types of pencil 2B and 4B.2B pencil was chosen due to the high sensitivity compared to 4B pencil. Sensitivity of the sensor is obtained 0.65 M/cm based on the deflection and output resistance. For the application, this sensor has been attached to the latex membrane and observation was made for the pressure measurement based on the applied pressure and different surface area.
