Abstract
An acceleration sensor includes an upper base plate; a lower base plate; and a gallium-based liquid metal encapsulated in graphene. The lower base plate includes a first surface including at least one diamond channel, and the upper base plate includes a second surface including a metal electrode corresponding to the at least one diamond channel in position; the liquid metal is disposed in a center of the at least one diamond channel; the first surface is bonded to the second surface through an adhesive; the liquid metal is movable in the at least one diamond channel and is in electrical contact with the metal electrode of the upper base plate during movement.
