Abstract
The present disclosure provides a system and method using a charge collection antenna in a wearable device to collect charge variation based on a user's jawbone and muscle motion. The collected charge variation may be used to determine an on-body status of the wearable device. For example, in wireless earbuds, information acquired from a charge collection antenna may be used to determine whether the earbud is worn in-ear by the user. The collected charge variation may also be used to detect jaw motion by the user.
