Abstract
The disclosure discloses an acceleration sensor, where the acceleration sensor comprises: a housing, and a mass block in the housing and connected with the housing via at least two hanging beams, where an auxiliary buffer component is further provided between the mass block and a bottom surface of the housing, and an elastic coefficient of the auxiliary buffer component decreases as force applied thereon increases.
Claims19
An acceleration sensor, comprising:
- a housing;
- a mass block in the housing and connected with the housing via at least two hanging beams;
- and an auxiliary buffer component between the mass block and a bottom surface of the housing;
- wherein an elastic coefficient of the auxiliary buffer component decreases as force applied thereon increases;
- wherein a filter frequency of the acceleration sensor decreases as the force applied thereon increases;
- wherein the auxiliary buffer component comprises a shear-thinning non-Newtonian fluid, and an elastic outer wall surrounding the shear-thinning non-Newtonian fluid.
