Abstract

This paper presents the Inkjet-printed strain gauge using PEDOT:PSS. The strain gauge (width 0.6 mm, length 20 mm, thickness $0.3{\mu}m$) was printed on the PET film using PEDOT:PSS ink. The resistance variation of the fabricated strain gauge was measured by the digital multi-meter with the displacement range of -4 to 10 mm. As the measured result, resistance variation (${\Delta}R/R_0$) has approximately 0.75%, linearity of 99.87%. The fabricated strain gauge is expected to the various applications such as tape type pressure sensor, PMS(pressure mapping sensor), wearable devices.
