The other end by attachment structure realize connect.
The most such as: flexible fixing strap 12 can be silica gel material, it is also possible to for soft plastic material, etc..
It should be noted that device Host 11 and flexible fixing strap 12 enclose the annulus setting formation when wearing, this annulus can
Think the annulus of closing, it is also possible to being the not closed circle with opening, this is not any limitation as by the embodiment of the present invention.
Optionally, device Host 11 may include that shell, the processor being positioned in shell and memorizer.Wherein, flexible solid
Surely the two ends with 12 with the shell of device Host 11 are connected, at least one metal strain plate 13 and at least one pair of metal electrode 14
All electrically connect with processor.Wherein, memorizer is used for storing instruction, the instruction that processor is stored in run memory,
The skin pricktest that the deformation resistance value realizing detecting according at least one metal strain plate detects with at least one pair of metal electrode
Lead value, determine whether wearable device is worn.
Optionally, metal strain plate 13 is two, and two metal strain plates 13 lay respectively at flexible fixing strap 12 and wearing
Time maximum two positions of deformation.
Owing to metal strain plate 13 is positioned at flexible fixing strap 12 position that deformation is maximum when wearing, therefore, metal strain
Sheet 13 can detect the deformation resistance value that flexible fixing strap 12 mechanical deformation causes fast and accurately, improves Intelligent Recognition and uses
Whether family wears efficiency and the accuracy rate of Intelligent worn device.
Optionally, metal strain plate 13 can be foil gage.
The radiating condition of foil gage is good, length fatigue life, production process simple, can promote making of wearable device
By performance, reduce cost, increase the service life.
Optionally, two metal electrodes 14 in pair of metal electrodes 14 are respectively positioned on flexible fixing strap 12 inside；Or, one
A metal electrode 14 in metal electrode 14 is positioned at device Host 11 internal, and another gold in pair of metal electrodes 14
Belong to electrode 14 and be positioned at flexible fixing strap 12 inside.
Optionally, the point symmetry on the basis of the center of annulus of two metal electrodes 14 in pair of metal electrodes 14 is arranged.
When measuring skin conductance value, two metal electrodes 14 are individually positioned in two positions of skin-proximal, a pair gold medal
The metal electrode 14 belonged in electrode 14 flows out micro-electric current, via skin section, and another in pair of metal electrodes 14
Metal electrode 14 flows into micro-electric current, determines skin conductance value by the magnitude of voltage between two metal electrodes 14 and current value.Institute
With, two metal electrodes 14 in pair of metal electrodes 14 are enclosed when wearing with device Host 11 and flexible fixing strap 12 and sets shape
On the basis of the center of the annulus become, point symmetry is arranged so that two metal electrodes in pair of metal electrodes 14 14 relatively away from
From farther out, the skin conductance value therefore detected is the most accurate, improves whether Intelligent Recognition user wears Intelligent worn device
Accuracy rate.
Optionally, the material of metal electrode 14 can be gold electrode.
Gold electrode itself electrode reaction is less likely to occur due to its chemical inertness, electrode, so that the skin pricktest obtained
Lead value more accurate, improve whether Intelligent Recognition user wears the accuracy rate of Intelligent worn device.

Concrete, metal strain plate 13 is positioned in flexible fixing strap 12, and mechanical deformation can be changed by metal strain plate 13
For deformation resistance value.When flexible fixing strap 12 does not deform upon, the metal strain plate 13 being positioned in flexible fixing strap 12 does not has
Deforming upon, now, the resistance that metal strain plate 13 detects will not change.When user wears wearable device, soft
Property fixing band 12 can occur the deformation matched with user's wearing position, and accordingly, metal strain plate 13 is along with flexible fixing strap
12 deformation produced also can produce deformation, and now, the resistance that metal strain plate 13 detects will change.Visible, obtain in real time
Take the resistance of each metal strain plate 13, the resistance of each metal strain plate 13 by getting, it can be determined that wearable set
The standby wearing conditions preset whether met in mechanical property.
Wherein, the wearing conditions preset is fixed for the flexibility reflected when user wears wearable device in wearable device
With the wearing conditions corresponding to the mechanical deformation of 12.
When user has worn wearable device, then wearable device be bound to meet preset wearing conditions, but anti-mistake
Come, when wearable device meets default wearing conditions, can not illustrate that user has necessarily worn wearable device, such as:
But user is only flexible fixing strap 12 to carry out bending situation about not wearing, therefore, in order to judge that user is accurately
No wear wearable device, when wearable device meets default wearing conditions, needed to continue to obtain every a pair metal electricity
The skin conductance value that pole 14 detects, is further judged according to skin conductance value, if every pair of metal electrodes 14 detects
The skin conductance value arrived, all in the range of default skin conductance value, the most finally determines that wearable device is worn by the user.
To sum up, the resistance that each metal strain plate 13 detects reflects the mechanical property of equipment, every pair of metal electrodes
14 skin conductance value detected reflect the Human Physiology characteristic after user wears wearable device, by plant machinery characteristic and
Human Physiology characteristic combines, such that it is able to determine whether wearable device is worn by the user accurately, improves Intelligent Recognition
Whether user wears the accuracy rate of Intelligent worn device.
It should be noted that the wearing conditions preset is configured as required, this is not done especially by the embodiment of the present invention
Limit.
Such as: all of metal strain plate 13 can corresponding same default wearing conditions, it is also possible to be different gold
Genus foil gauge 13 is to there being the corresponding wearing conditions preset, when different metal strain plates 13 is to there being the corresponding pendant preset
When wearing condition, default wearing conditions can be identical, it is also possible to different.
It should be noted that according to the resistance of each metal strain plate, it is judged that whether wearable device meets the pendant preset
Wear condition, can be the resistance of all metal strain plates wearing conditions that is satisfied by presetting, it is also possible to be whole metal strain plates
The resistance of middle part metals foil gauge meets default wearing conditions, and this is not particularly limited by the embodiment of the present invention.
It should be noted that the skin conductance value scope preset is configured as required, the embodiment of the present invention is to this not
It is particularly limited.
Such as: can be that all of metal electrode is to corresponding same default skin conductance value scope, it is also possible to be not
