Research on characterization of flexible capacitive tactile sensor based on scratch coating microstructure
Flexible tactile sensor with excellent performance,durability,high preparation efficiency and low cost is an urgent need for intelligent electronic skins,human-robot interaction,and healthcare.Most microstructured capacitive tactile sensors requires cleanroom for micro-fabrications that increase the complexity and the cost of the manufacturing process.An innovative and simple method is introduced to fabricate different sized microstructures on the surface of the poly(vinylidene fluoride-co-hexafluoropropylene)(PVDF-HFP)ionic gel membranes with simple tools.Sensing characteristics are tested and compared.Experiments show that the sensor has comprehensive advantages such as high sensitivity(46.8 kPa-1),low detection limit(16 Pa),rapid response time(20 ms)within pressure range of 1.2 kPa.After 6 000 cycles high pressure loading,it doesn't deviating from the initial performance and has strong robustness and practicality.The proposed method can significantly enhance the preparation efficiency and overall performance at the same time of reducing the money and time cost on manufacture processes.
