In this work, we present the development of a reliable piezoresistive strain sensing array fabricated by a solution based thin film method. The strain sensing array were made on a polyimide (PI) substrate by patterned hydrophilic treatment and tilted-drop process. The technique of patterned surface modification was performed by atmospheric plasma for enhancing surface energy in specific area. The measured water contact angles were 118.8° and 0.9° before and after hydrophilic treatment respectively. The materials used in the tilted-drop process were conductive polymer composites solutions with different ingredients and proportions. Fabricated strain sensor samples with different conductive fillers, including carbon nano-fiber, multi-wall carbon nano-tube and carbon black, and different surfactants, including sodium dodecyl sulfate (SDS) and polystyrene sulfonate (PSS), have been investigated by measuring resistivity in different strain. Finally, the fabricated strain sensing array has been tested by using a LabView program to capture the multi-meter values of resistivity. A scanning circuite were also developed to capture the signal from the flexible sensing array. The developed system has been applied to human posture correction and artificial muscle research.
