Abstract

The embodiment of the invention provides a capacitive sensor, a wearing detection device and wearable equipment. The capacitive sensor comprises a first detection electrode layer, a second detection electrode layer and a shielding electrode layer, the first detection electrode layer is insulated from the second detection electrode layer; the first detection electrode layer is used for detecting a first capacitance signal applied to the inner side of the wearable device; the second detection electrode layer is used for detecting a second capacitance signal applied to the outer side of the wearable device; the shielding electrode layer is used for shielding the second detection electrode layer when the first detection electrode layer detects the first capacitance signal; when the second detection electrode layer detects the second capacitance signal, the first detection electrode layer is shielded; the first capacitance signal and the second capacitance signal are used for determining the wearing state of the wearable device.

Description

technical field [0001] The embodiments of the present application relate to the technical field of wearable devices, and in particular, relate to a capacitive sensor, a wearing detection device, and a wearable device. Background technique [0002] The traffic law stipulates that drivers or passengers must wear helmets when driving electric vehicles or motorcycles, but many drivers and passengers of electric vehicles or motorcycles have not established the awareness of wearing helmets, which seriously affects the road. Traffic safety and own safety. [0003] In the prior art, a detection electrode is arranged in the helmet, and based on the capacitive signal sensed by the detection electrode to judge whether the helmet is worn, the sensitivity is high and the structure is simple. However, the disadvantage of this solution is that when the user's hand or other objects touch the outside of the helmet, it is easy to misjudge that the helmet is in the wearing state, resulting in...
