摘要： A device and a method for producing haptic feedback are disclosed. In an embodiment a device includes at least one piezoelectric actuator having a plurality of piezoelectric layers and internal electrodes arranged therebetween, a first amplification element and a second amplification element, wherein the piezoelectric actuator is arranged between the amplification elements, wherein the piezoelectric actuator is configured to change its extension in a first direction upon application of an electrical voltage, and wherein the amplification elements are configured to deform as a result of the change in the extension of the piezoelectric actuator such that a subregion of a respective amplification element is moved relative to the piezoelectric actuator in a second direction, which is perpendicular to the first direction and a driver circuit configured to apply the electrical voltage to the piezoelectric actuator such that the amplification elements are deformed thereby producing the haptic feedback against an object pressing on the device, the haptic feedback imitating a jump in force.

摘要： A touch sensing device including an panel including an operation face, a touch sensor fixed to the panel, a circuit board being spaced from the opposite face opposite to the operation face of the panel, an electronic component on a first face of the board, an opposing part in opposing spaced relation to a second face of the board, a coupling member coupling the panel to the board on an outer side relative to the touch sensor and the electronic component, and a switch between the second face of the board and the opposing part. An optical path extends from the electronic component through the touch sensor and the panel. The board relatively approaches the opposing part in accordance with the forward movement of the panel and relatively moves away from the opposing part in accordance with the backward movement of the panel. The switch produces or changes an output signal in accordance with the approach of the board.

摘要： A domestic appliance has an operating element, the operating element comprising a carrier, at least one pressure sensor configured for detection of an operation of the operating element, and at least one light source. A control is configured to switch the light source on or off subject to a sensor signal coming from the pressure sensor. At least one light conductor is arranged close to the light source and is configured to conduct light from the light source to at least a side of the light conductor remote from the carrier. Provided on or close to the side of the light conductor remote from the carrier is a screen comprising at least one opaque part and at least one translucent part, which together form a symbol.

摘要： Various embodiments may provide a pressure sensing electronic device. The electronic device may include a tactile sensor configured to determine an external pressure. The electronic device may also include a memory device electrically coupled to the tactile sensor. The memory device may be configured to switch from a first state to a second state upon the external pressure determined by the tactile sensor exceeding a predetermined threshold when a writing current flows through the tactile sensor and the memory device.

摘要： An electronic device may have a housing in which components such as a display are mounted. A strain gauge may be mounted on a layer of the display such as a cover layer or may be mounted on a portion of the housing or other support structure. The layer of material on which the strain gauge is mounted may be configured to flex in response to pressure applied by a finger of a user. The strain gauge may serve as a button for the electronic device or may form part of other input circuitry. A differential amplifier and analog-to-digital converter circuit may be used to gather and process strain gauge signals. The strain gauge may be formed form variable resistor structures that make up part of a bridge circuit that is coupled to the differential amplifier. The bridge circuit may be configured to reduce the impact of capacitively coupled noise.

摘要： Certain example embodiments include a press sensor element that includes a piezoelectric layer having a first surface in communication with a first layer, the first layer including a first conductive region, where the first conductive region covers at least a central portion the first surface. The sensor element includes a second surface in communication with a second layer, the second layer including a second conductive region, a third conductive region, and a first non-conductive void region separating the second conductive region and the third conductive region. An area of the first conductive region is configured in size relative to an area of the third conductive region to substantially reduce a thermally-induced voltage change between two or more of the first, second, and third conductive regions responsive to a corresponding temperature change of at least a portion of the piezoelectric layer.
