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). The readout circuit is configured to obtain measured values respectively corresponding to the at least two different sensitive elements (1, 2, . . . , n). Different types of sensitive elements (1, 2, . . . , n) are designed as linear structures at equal spacings to ensure consistency of the different sensitive elements (1, 2, . . . , n) in a sensing region.

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.
