Abstract: A smartwatch includes a watch body, an airbag, and a sensor. The watch body is electrically coupled to the sensor. The sensor is disposed on an inner wall of the airbag. When the smartwatch is worn on a wrist of the user, the airbag and the sensor cover the radial artery of the wrist. The sensor is configured to measure the plurality of pulse waves of the radial artery when the airbag is under different pressure strength. The watch body is configured to determine the blood pressure of the user based on the plurality of pulse waves.

Abstract: An electronic device receives a first operation, and performs route planning based on a target graphic indicated by the first operation and a preset target region. The electronic device obtains a target route in the target region based on the target graphic and the target region, and displays the obtained target route on a map.

Abstract: A sensor includes: two friction layers and at least one electrode layer. The two friction layers are respectively made of materials with different electron gain and loss capabilities, and a surface of at least one friction layer includes a multi-level micro-nano structure, so that when there is pressure, equal-quantity and opposite net charges corresponding to the applied pressure are induced on the two friction layers. The multi-level micro-nano structure includes micro-nano columnar structures with at least two different heights. The electrode layer is configured to generate a current based on the net charges. The multi-level structure with different heights is designed.

Abstract: A multifunctional sensor includes a substrate and a sensitive layer located on the substrate. The sensitive layer includes at least two different sensitive elements (1, 2, . . . , n) for responding to at least two different types of ambient signals. The sensitive elements (1, 2, . . . , n) are in linear structures, and the linear structures are arranged at equal spacings. The sensitive layer further includes at least two electrode pairs for connecting to a readout circuit. One electrode pair corresponds to one sensitive element (1, 2, . . . , n).

Abstract: A pose estimation method and an apparatus are provided, to obtain a more accurate pose estimation result. The method includes: obtaining a first event image and a first target image, where the first event image is aligned with the first target image in time sequence, the first target image includes an RGB image or a depth image, and the first event image includes an image indicating a movement trajectory that is of a target object and that is generated when the target object moves in a detection range of a motion sensor; determining integration time of the first event image; if the integration time is less than a first threshold, determining that the first target image is not for performing pose estimation; and performing pose estimation based on the first event image.

Abstract: One example image sensor includes a metasurface, a substrate, and an optical-to-electrical converter. Arrays in the metasurface are arranged on the top of the substrate. The metasurface includes multiple subunits. Each subunit includes an array including multiple columnar structures. The bottom of the substrate is disposed on a surface of the optical-to-electrical converter in the image sensor. The metasurface includes at least two media with different refractive indexes. The optical-to-electrical converter includes an array for optical-to-electrical conversion. The array of the optical-to-electrical converter is divided into multiple color regions. The metasurface is configured to refract incident light and transmit, through the substrate, refracted light to a corresponding color region in the array of the optical-to-electrical converter. In addition, each subunit refracts incident light and then transmits refracted light to a color region in a corresponding color unit.
