Abstract: A projective capacitive force sensing structure is provided. The projective capacitive force sensing structure includes a first substrate, a first electrode, a first capacitance material layer, a second substrate, a second electrode and a third electrode. The stacking order of the projective capacitive force sensing structure is from the first substrate to the second substrate. The second electrode and the third are respectively below and above the second substrate. A first signal is detected between the first electrode and the second electrode and is collected by the first electrode. A second signal is detected between the second electrode and the third electrode and is collected by the third electrode. A force applied by an object is determined according to the first signal and a location of the object is determined according to the second signal. Both the force applied by an object and the location of the object are acquired.

Abstract: A force sensing structure and a force sensing device including the same are provided. The force sensing structure is configured to detect a proximity of an object to the force sensor from an upside and a force applied by the object to the force touch sensor. The force sensing structure includes a first electrode and a first capacitance material layer. The first capacitance material layer is disposed adjacent to the first electrode. When the object approaches the force touch sensor, the force touch sensor is configured to detect the proximity of the object according to a first capacitance variation, and when the object contacts the force sensor and deforms of the first capacitance material layer, the force touch sensor is configured to detect the force applied by the object according to a second capacitance variation.
