摘要： Embodiments include a temperature sensing device that includes a temperature sensor stack that includes a flexible substrate and an array of temperature sensors coupled to the flexible substrate. Each temperature sensor in the array of temperature sensors can include a conductive material defining a continuous pattern extending from a first node to a second node, a first set of conductive traces coupled to the flexible substrate, and a second set of conductive traces coupled to the flexible substrate. The temperature sensing device can include a processing circuit configured to apply an electrical signal across the conductive material of each temperature sensor using the first set of conductive traces, detect an effect of the conductive material of each temperature sensor on the electrical signal using the second set of conductive traces, and determine a temperature for the temperature sensors in the array using the detected effects of the conductive material on the electrical signal.

摘要： An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

摘要： An electronic device is configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. The localized haptic feedback is provided by an array of piezoelectric haptic actuators below the surface of the electronic device. Actuators within the array of piezoelectric haptic actuators are separately controllable by a control circuit layer. The control circuit layer includes control circuitry, a master flexible circuit which passes between rows of actuators, and an array of slave flexible circuits. Each slave flexible circuit is connected to the master flexible circuit and an actuator. In further examples, the array of piezoelectric haptic actuators provides a unified structure for detecting touch and force inputs.

摘要： An electronic device configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. A support structure is positioned below the surface, and one or more haptic actuators are coupled to the support structure. In some examples, the support structure is shaped or configured to amplify a response to a haptic actuator. When a haptic actuator is actuated, the support structure deflects, which causes the surface to bend or deflect at a location that substantially corresponds to the location of the activated haptic actuator. In some examples, prior to providing haptic feedback, at least one haptic actuator is electrically pre-stressed to place the haptic actuator(s) in a pre-stressed state. When haptic feedback is to be provided, at least one haptic actuator transitions from the pre-stressed state to a haptic output state to produce one or more deflections in the surface. In other examples, a haptic structure incorporates a piezoelectric element that is shaped to reduce the overall cost of the haptic structure while still providing high actuation performance.

摘要： An electronic device such as a wristwatch may be provided with conductive structures. The conductive structures may include a sensor electrode for an electrocardiogram (ECG) sensor. A coating may be disposed on the sensor electrode to reflect particular wavelengths of visible light so that the sensor electrode exhibits a desired color. The coating may include adhesion and transition layers on the sensor electrode, an opaque coloring layer on the adhesion and transition layers, and a thin-film interference filter on the opaque coloring layer. The thin-film interference filter may have an uppermost diamond-like carbon (DLC) layer. The DLC layer may contribute to the color response of the coating while concurrently minimizing noise in ECG waveforms gathered by the ECG sensor using the sensor electrode.

摘要： In some embodiments, a haptic actuator includes piezoelectric material and a pattern of voltage electrodes coupled to a surface of the piezoelectric material. The voltage electrodes are individually controllable to supply voltage to different portions of the piezoelectric material. Different sections of the piezoelectric material are operable to deflect, producing haptic output at those locations, in response to the application of the voltage. Differing voltages may be provided to one or more of the voltage electrodes to affect the location of the deflection, and thus the haptic output. In various embodiments, a haptic output system incorporates a sealed haptic element. The sealed haptic element includes a piezoelectric component that is coupled to one or more flexes and is sealed and/or enclosed by the flex(es) and an encapsulation or sealing material.
