FORCE SENSING STRUCTURE AND FORCE SENSING DEVICE INCLUDING THE SAME
First Claim
1. A force sensing structure comprising:
- a force touch sensor configured to detect a proximity of an object to the force touch sensor from an upside and a force applied by the object to the force touch sensor, which comprises;
a first electrode disposed separately from the object with a gap; and
a first capacitance material layer disposed adjacent to the first electrode,wherein 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 change therebetween,and when the object contacts the force touch sensor and at least a portion of the force is applied to the first capacitance material layer, the force touch sensor is configured to detect the force applied by the object according to a second capacitance change therebetween.

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.
