The resonant tunneling structure (RTS) micro gyroscope based on nano-film was proposed. The meso-piezoresistive effect of RTS was analyzed; the material structures of RTS and its processing methods were designed; the RTS that can reflect the resonant tunneling effect was fabricated. The structure can reduce the parasitic capacitance of the sensor, improve the negative resistance characteristics of the sensitive film, and be used in micro gyroscope. The structural design and simulation of micro gyroscope based on resonant tunneling effect were carried out; the micro gyroscope was manufactured using bulk micromachining technology, and its key performance parameters were tested.
