    The invention discloses an amplitude and frequency two-parameter sensing decoupling system based on a friction nanometer generator, a resistance type sensor and an inductance type sensor which are connected in parallel are adopted to form a resonance detection circuit, the resistance type sensor senses the magnitude change of force, and the inductance type sensor senses the change of the position of an object. And the friction nanometer generator is connected in series with the resonance detection circuit to supply power to the system, so that an amplitude and frequency two-parameter sensing decoupling system is formed. In the system output decoupling process, firstly, the change relation between the output frequency and power of the inductive sensor and the distance of a measured object is measured, then, the change relation between the output amplitude of the system and the distance and weight of the measured object is measured, and finally, the distance and weight of the calibrated object are calculated by utilizing the known distance and weight of the calibrated object and combining the change of the output frequency and amplitude of the system. The measured distance and force value are obtained through decoupling in a table look-up mode.
