Other AbstractThe invention relates to a technology for measuring micro Newton force based on a PVDF piezoelectric material, particularly a system for measuring submicro Newton force which comprises a micro force perception measuring head, a signal disposal circuit and a data acquisition module, wherein the micro force perception measuring head receives micro force from a probe, converts a force signal to electric charge and then sends the electric charge to the signal disposal circuit the signal disposal circuit converts the electric charge into a sizable and detectable pressure signal and sends the pressure signal to the data acquisition module the data acquisition module conducts A/D convert of the received pressure signal and converts a pressure value into a micro force value by using the relationship between the calibrated micro force and the output pressure of the signal disposal circuit. The technology solves the problem of measuring submicro Newton contact force during the micro assembling process, and is mainly used in the technical fields of micro/nano machining, assembling, etc.
