Fadzil, Mohd Faris and Mohd Sidek, Roslina and Jaafar, Haslina and Hamidon, Mohd Nizar (2017) Fabrication and characterization of carbon-based flexible strain sensor. In: 2017 IEEE Regional Symposium on Micro and Nanoelectronics (RSM), 23-25 Aug. 2017, Penang, Malaysia. (pp. 203-206).


This research covers carbon-based strain sensors which are designed and printed onto flexible substrates. Conductive nanocomposite of Polydimethylsiloxane (PDMS) and Carbon Black (CB) powder with 10% of CB have been used as the sensing element utilizing its flexibility and conductivity while silver conductive paste is used as the electrode for the strain sensor. Several designs with different length of strain sensors were printed using screen printing technology onto 0.75μm-Kapton HN film. Printed sensors were then cured at 85°C (for carbon printing) and 145°C (for silver printing). Parameters characterized are resistivity, conductivity and stretchability of the sensor using tensile test. The relationship between force, strain and resistance for all sensors designed are also discussed. The measured resistivity and conductivity of the sensor are 0.43 Ωm and 2.4 S/m respectively while the stretchability of the sensor on Kapton film has a maximum strain of 45%. This flexible strain sensor is very useful in many applications such as health monitoring systems, human motion detection and many more.
