Wearable devices

A wearable device, comprising:

• a wearable body, configured to cover a joint position of a user;
• and
• at least one inductive sensor, including an inductive structure wound by a conductive wire, wherein the at least one inductive sensor is attached to the wearable body at a position corresponding to the joint position of the user, and the inductive structure generates a varying inductance in response to a deformation at the joint position, wherein
• the inductive structure includes a spiral inductive coil;
• the wearable body comprises a glove, wherein when the user wears the wearable device, at least a portion of the at least one inductive sensor is disposed at a joint of a hand of the user to collect a motion signal of the hand of the user;
• the at least one inductive sensor is disposed on back of the hand or in a palm of the user,
• the at least one inductive sensor disposed on the back of the hand of the user further includes a magnetic conductive film only covering a side of the spiral inductive coil away from the hand of the user;
• the at least one inductive sensor disposed in the palm of the user further includes a magnetic conductive film only covering a side of the spiral inductive coil near the hand of the user;
• and
• a resistance of the inductive structure is less than 100 Ω.
