A method for calibrating and/or verifying an implantable detecting device and an implantable detecting device are provided. The method includes: outputting a square wave signal to an implantable detecting device that has been implanted into a subject, where the implantable detecting device is configured to detect a concentration of an analyte in the subject, and a potential of the square wave signal increases incrementally over time; receiving a first current signal produced by the implantable detecting device in response to the square wave signal; generating a calibration curve based on a correspondence between the first current signal and the square wave signal; and performing calibration and/or functional verification on the implantable detecting device based on the calibration curve.

The example of the present application provides a physiological signal sensing method and apparatus, and an electronic device, where an apparatus part includes: one or more light emitters which are used for emitting first light; one or more photoelectric sensors which are used for detecting second light obtained through reflecting the first light via biological tissue and generating a corresponding first signal; a capacitive sensor which is used for detecting changes of a capacitor which is in contact with the biological tissue and generating a corresponding second signal; and a signal processing module which is used for carrying out motion artifact elimination on the first signal according to the second signal, so as to obtain a third signal. In some examples, the one or more photoelectric sensors are multiplexed as the capacitive sensor. Spatial correlation between the first signal and the second signal is higher, and then a better motion artifact elimination effect is achieved.

A method for processing a signal, a method for acquiring data, and an electronic device are provided. The method includes: processing, based on first parameter information stored in a parameter register, an analog signal obtained by sampling a to-be-measured signal to obtain a first digital signal; replacing, when receiving second parameter information sent by a second processing module, the first parameter information in the parameter register with the second parameter information; and processing the analog signal obtained by sampling the to-be-measured signal, based on the second parameter information stored in the parameter register to obtain a second digital signal, and setting a target identifier for a first digital signal of the second digital signal obtained through processing based on the second parameter information.
