Abstract
A force sensing device and a force sensing system are provided. The force sensing device comprises at least one magnetic material layer and a force sensing layer which can move with respect to each other. The force sensing layer comprises two sensing elements. The first sensing element, disposed along a first axis of the magnetic material layer, generates a sensing signal varying with a first lateral force applied on the force sensing device. The first lateral force enables the first sensing element to move relatively with respect to the magnetic material layer along the first axis. The second sensing element, disposed along a second axis of the magnetic material layer, generates a sensing signal varying with a second lateral force applied on the force sensing device. The second lateral force enables the second sensing element to move relatively with respect to the magnetic material layer along the second axis.
