Abstract
A touchpad and a sending unit for the same are provided. The sensing unit has two electrode layers and a separation assembly. The separation assembly has multiple deformation rooms and multiple gap assemblies. The deformation rooms communicate with the gap assemblies. The gap assemblies communicate with the exterior environment. When the upper electrode layer is pressed and deforms in the deformation rooms, the air in the deformation rooms is discharged through the gap assemblies so that the air does not accumulate in the remaining unstressed spaces to avoid resistance and to maintain the normal operation of the force sensing function.
