The detection and heating circuit includes a detection and heating material. When the detection heating material works in a detection mode, the detection and heating circuit obtains a bioelectric signal of a user by using the detection and heating material. The control circuit instructs, according to the bioelectric signal, the detection heating circuit to switch a working mode of the detection and heating material to a heating mode; and instructs the detection and heating circuit to determine heating duration and/or a heating temperature of the detecting and heating material. The apparatus may be used in the field of artificial intelligence. Through control of the control circuit, the detection heating material can have both detection and heating functions. Intelligent perception of a state of the user is implemented by detecting of the bioelectric signal.

Disclosed is a method for fabricating a wearable hydrogel glucose sensor, belonging to the technical field of biomedical sensing, including using polyacrylamide hydrogel as a basic material, preparing a hydrogel film by adding with phenylboronic acid group capable of recognizing glucose molecules, and carrying out grating writing on the hydrogel film in a femtosecond laser direct writing mode to obtain the wearable hydrogel glucose sensor. The hydrogel film combines with glucose and expands linearly, which makes the grating period and effective refractive index change. The quantitative measurement of glucose is realized by detecting the spatial position of diffraction band and the change of diffraction power intensity.
