▎ 摘　　要

NOVELTY - The utility model claims an acceleration sensor device of symmetrical graphene nano belt, wherein, comprises base layer and bottom layer, on substrate layer of the surface provided with the same size and symmetrical arrangement of the first strip shape graphene nano belt and between the second strip-shaped graphene nano belt, said first strip shape graphene nano belt, the second strip-shaped graphene nano belt provided with micro-nano optical fiber vertical waveguide. Said first strip shape graphene nano belt, the second strip-shaped graphene nano belt form graphene-medium-graphene symmetrical surface plasma waveguide structure. The device by regulating thickness of the optical fiber waveguide, realizing regulation surface plasma mode of transmission characteristics, to control input signal resonance wavelength peak value, so as to control the sensitivity of sensor. The device makes up of microelectronics machine sensor system by the outside world environment, insufficient oneself and property limit, improving traditional micro-sensor response time long, low sensitivity problem equal.
