Other AbstractThe utility model relates to the micro Newton force measuring technique, based on the PVDF piezoelectric material, in particular to a measuring device for the sub-micro Newton grade force, comprising a micro-force sensing measuring head, a signal conditioning circuit and a data acquisition module wherein, the micro-force sensing measuring head receives the micro-force from a probe and converts the force signal into the electric charge which is transmitted to the signal conditioning circuit the electric charge is converted into voltage signal which can be detected and has proper size by the signal conditioning circuit and is outputted to the data acquisition module the data acquisition module applies A/D conversion on the obtained voltage signal and converts the voltage value into micro-force numerical value according to the relationship of the calibrated micro-force and the outputted voltage of the signal conditioning circuit. The measuring device for the sub-micro Newton grade force is adopted to solve the problem of measuring the sub-micro Newton contact force during the micro assembly process and is mainly applicable to the submicron scale machining and the assembly technical fields.
