A multifunctional sensor and a device are disclosed. The multifunctional sensor may be used on a surface of a device, for example, a surface of a wearable device, and include a substrate (201) and a sensitive layer (202). The sensitive layer (202) is located on the substrate (201). The sensitive layer (202) 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 (202) 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. During use, specific values of a plurality of ambient signals, from which noise interference has been removed, of the multifunctional sensor are calculated based on the measured values obtained by the readout circuit. In this way, a plurality of sensing values can be simultaneously measured on the surface of the device at a time.
