Abstract
Systems, methods, and detection apparatuses, for the detection of body capacitance, such as the capacitance of a human body, are disclosed. A detection apparatus determines an electronic signal characteristic of one or more electrodes. The electronic signal characteristic can be based on a voltage. Responsive to the electronic signal characteristic being within a predetermined electronic signal characteristic range, a charging mode is activated. Responsive to the electronic signal characteristic of the one or more electrodes being outside the predetermined electronic signal characteristic range, a capacitance detection mode is activated. The capacitance detection mode includes: determining a capacitance value of the one or more electrodes in which the capacitance value is based on a frequency of change in a capacitance associated with the one or more electrodes. Responsive to the capacitance of the one or more electrodes exceeding a capacitance threshold, activating a wearable mode.
