Description
technical field [0001] The present disclosure relates to the technical field of wearable devices, and in particular, to a detection circuit, a detection method for a wearable device, and a wearable device. Background technique [0002] Wearable devices such as smart watches, bracelets, and wristbands often need to detect the wearing status to determine whether the wearable device is worn. At present, wearable devices mainly detect the wearing status through capacitive touch sensors. By touching the human body to change the capacitance of the capacitive sensor, and then determine the wearing state. However, in practical applications, the detection of capacitive sensors is susceptible to interference. For example, metal conductors or clothing touching the capacitive sensor will cause changes in the capacitance of the capacitive sensor, which will lead to incorrect detection results. [0003] It should be noted that the information disclosed in the above background section is...
