The invention relates to a process for preparing ultra-thin compliance conductive high polymer sensitive film in the thrust transducer technique field. The process comprises that the conductive plateblack pigment powder with the mean diameter less than 1 mum, 10-50nm SiO2 dispersant powder and liquid single component silicon rubber are mixed in more than 95% acetone organic solvent, are mixed mechanically in the ultrasonic in order to achieve gel state mixture, are mixed mechanically and continuously in order to volatilize acetone, the mixture is moulded into 70-100 mum conductive high polymer film, the conductive high polymer film is vulcanized and is formed the good elastic film. The film material with the method has the thin structure, the good compliance, the big measuring range, the high accuracy and the high resolution ratio and the like, which is suitable for the on-line monitoring of the contact force and the compressional force at the intermediate of the curved surface in the industry production process and the body medical treatment rehabilitation process.
