A wireless tire pressure monitoring system powered by a friction nanometer generator and a battery in a hybrid mode comprises the friction nanometer generator, a pressure and temperature detection module, a sensor MCU, an RF module, the lithium battery, a switch control circuit and a voltage stabilizing circuit. The friction nanometer generator passes through the rectifier and then is connected to two ends of the super capacitor and the voltage stabilizing circuit in parallel; and the voltage stabilizing circuit and the battery supply power to the pressure and temperature detection module, the sensor MCU and the RF module which are connected in series through the switching circuit. The system is slightly modified on the basis of an existing commercial tire pressure monitoring device, the stability and the practicability are better, and the service life of the built-in tire pressure sensor can be effectively prolonged. The structure is smaller and simpler, and the market prospect is good.
