Abstract: Disclosed are a wearable device, a signal processing method and a wearable system, the wearable device includes a receiving electrode and a control circuit of the wearable device. The receiving electrode can receive an excitation signal sent by a transmitting wearable device through the skin of the user. The control circuit of the wearable device is used to obtain the present skin impedance of the user through the receiving electrode and adjust the gain of the excitation signal; and when the excitation signal is received, the excitation signal is amplified based on the adjusted gain to determine the present click position of the user.
