1. An acceleration sensor comprising:
two polarizing plates disposed in a crossed Nicol disposition;
a sensitive color plate; and
a silver nanowire dispersion configured to change in an orientation within the acceleration sensor due to an acceleration, wherein
the sensitive color plate and the silver nanowire dispersion are disposed between the two polarizing plates, and
the acceleration sensor is configured to indicate the acceleration by the sensitive color plate being configured to show an interference color that changes based on the change in the orientation of the silver nanowire dispersion due to the acceleration.
