A touch pad, comprises a housing comprising a vibration device, a cover, a capacitive sensing layer electrically connected to a processor and a pressure sensing layer arranged in the housing, also electrically connected to the processor. The capacitive sensing layer is positioned between the cover and the pressure sensing layer. The processor is configured to utilize a signal output from either the capacitive sensing layer or the pressure sensing layer to activate the vibration device.

Touch pad

A touch device comprises a base, a membrane pressure sensor arranged on the base, a touch sensing layer covering the membrane pressure sensor, and a force feedback structure arranged on the lower surface of the touch sensing layer and electrically connected to the membrane pressure sensor. The membrane pressure sensor is configured to generate a pressing signal related to the force applied to it, and the force feedback structure is configured to receive the pressing signal and generate a feedback force corresponding to it.

Touch device

An apparatus for use in the assembly of an electronic device, such as a mobile telephone, comprises a pressure sensor. The pressure sensor is embedded within an inner elastic layer and the inner elastic layer is embedded within an outer elastic layer. The inner elastic layer has an elastic modulus which is greater than the elastic modulus of the outer elastic layer.

Electronic device comprising a pressure sensor

An electronic keyboard comprises a plurality of keys and a housing comprising a cavity. The cavity accommodates a circuit board, a pressing layer and at least one pressure sensor arranged therein. Each pressure sensor is provided between a lower portion of the cavity and the circuit board, the pressing layer is moveably connected to each of the keys and the circuit board is provided between the pressing layer and the lower portion. Each pressure sensor is connected to the circuit board, and a force-receiving surface of each pressure sensor aligns with a projection area of the corresponding one of the keys.

Electronic keyboard

A button structure has a base having a slot and a sensing element inserted into the slot. A pressure concentration element is fixedly connected by bonding to the sensing element and a key cap is mounted to the base. The key cap has a core member fixedly connected to a lower surface of a top plate of the key cap. The lower surface of the core member can be brought into contact with the pressure concentration element on application of a pressure to an upper surface of the top plate, such that the applied pressure is transmitted to the sensing element through the core member and the pressure concentration part. The sensing element is a piezoresistive film sensor.

Button structure

A pressure sensor comprises a first sensing module comprising a first negative electrode and first support structures arranged at intervals on the first negative electrode. A first flexible insulating layer covers an upper surface of the first support structures and first positive electrodes are arranged at intervals on a lower surface of the first flexible insulating layer and distributed between the first support structures. A second sensing module comprises a second negative electrode disposed on the first flexible insulating layer and second support structures are arranged at intervals on the second negative electrode. A second flexible insulating layer covers an upper surface of the second support structures. Second positive electrodes are arranged on a lower surface of the second flexible insulating layer at intervals and distributed between the second support structures. The first support structures are offset from the second support structures.
