Abstract
A wearable device with removal-detection function includes a component, a copper foil, a wireless communication circuit, and a monitoring unit. The copper foil is arranged in the component. An induction capacitor is formed between the copper foil and user's body when the component is in contact with user's body. The monitoring unit measures electrical characteristics of the induction capacitor, and can determine a removal from user's body based on the measured electrical characteristics. The monitoring unit further controls the wireless communication circuit to send a warning message plus location information to a monitoring terminal if the wearable device is removed.
