A touch sensor comprises two baseplates arranged at intervals, a first electrode disposed between the baseplates, and a pressure sensing module. Two-dimensional touch control of the sensor is achieved by the first electrode. An insulating material is provided between the module and the first electrode. The module comprises a second electrode based on the insulating material and disposed on a side of the insulating material away from the first electrode, and a third electrode disposed above the other one of the baseplates. The second electrode is not in contact with the third electrode, an air gap is provided between the second and third electrodes, the second and third electrodes are respectively connected to a signal output source. When one of the baseplates close to the second electrode is touched, the air gap changes a spacing to change a self-capacitance signal of the signal output sources.

Touch sensor

A touch sensor comprises two baseplates, a first electrode, a second electrode and a variable geometry electrode, the baseplates are arranged at intervals, and a first distance formed therebetween, the first electrode is arranged on one of the two baseplates and has a first projected area, the second electrode is arranged on one of the two baseplates same as the first electrode arranged, and a second distance formed between the second electrode and the first electrode, a variable geometry electrode is arranged on the other one of the two baseplates different from the first electrode, and relative positions between the variable geometry electrode and the first electrode selected from one of following: the variable geometry electrode is partially located within the first projected area of the first electrode, the variable geometry electrode is not located within the first projected area of the first electrode.

A knob device for disposing on a touch screen, comprising a base provided with a plurality of recovery elastic components; and an operating cap disposed on the base. The operating cap have a rotation stroke and a pressing stroke, and is provided with a plurality of touch control pads, each of the pads has a working surface. The working surface of at least one of the touch control pads is not at a same height as the working surfaces of the other touch control pads. When the rotation stroke is performed, the working surfaces of some of the touch control pads contact the touch screen to activate a rotational touch control. When the pressing stroke is performed, the working surfaces of the touch control pads contact the touch screen jointly to activate a click and touch control.
