Description

Technical Field

[0001] The invention relates to a capacitive sensor capable of identifying body movements. Background Art

[0002] Existing capacitive sensors used to identify the category of limb approach actions are all set on flexible materials. This setting method is based on the contact between the limb and the flexible material with capacitive sensing. The surface of the flexible material will deform, so that the vertical distance between the two electrodes of the capacitive sensor changes, causing the capacitance value of the capacitor to change, thereby determining the pressing action of the limb.

[0003] The use of this capacitive sensor set on a flexible material is very limited. In many occasions, such as car glass, induction cookers, and washing machines, this sensor used to identify the approaching movement of limbs cannot be used. Therefore, it is very necessary to develop a capacitive sensor that can be set on a hard material and can identify the movement category of the limbs, so that the product can perform different functions.
