Description
Technical field
The invention belongs to intelligent wearable garment technical fields, are related to a kind of close-fitting movement of movable intelligence of reflection skeletal muscle
Dress ornament, the in particular to intelligent close-fitting sports garment decorations of a kind of reflection skeletal muscle diastole and contraction movement.
Background technique
Intelligent wearable device market is developed rapidly in recent years, and product emerges one after another.Common intelligence wearing is set on the market
It has very much, such as has the function of bracelet containing rhythm of the heart and step function, is able to record sleep quality and heart unusual fluctuation feelings
The intelligent vest of condition, the Intelligent heart rate band with gyroscope and environment monitoring function and the intelligence that Various types of data in running can be recorded
Energy running shoes have all been researched and developed successfully and have been listed.However, being able to reflect skeletal muscle in movement in existing intelligent wearable device
Shrink and diastole situation and the product that is recorded and analyzed it is actually rare.
In the prior art, 2014/0135593 A1 of patent US (Wearable architecture an method for
Performance monitoring, analysis and feedback) disclose a kind of plural bio-signal sensor of utilization
Different parts electromyography signal is acquired, then carries out the sportswear of data analysis, to reflect professional athlete's athletic performance.So
And firstly, biosensor limited amount used in the product, while being used again at the different position of body due to it same big
The sensor of small, same contact area, data collected are simultaneously imperfect and accurate；Secondly, to solve to use bio-sensing
The washing problem of the clothes of device, contact skin layer uses silica gel, and when Athletess are largely perspired, the body-sensing of product is relaxed
Adaptive is very poor；Finally, being connected between biosensor using printed circuit, printed circuit and biosensor are substantially inelastic,
So that compensatory deformation occurs for other position fabrics of clothes, so that the overall beautiful and monitoring accuracy of product is influenced, in short, its product
There are also many improved possibility on wearing comfort and monitoring data accuracy.
A kind of comfortable and easy to wear and high measurement data accuracy the movable intelligence of skeletal muscle is able to reflect it would therefore be highly desirable to study
Close-fitting sports garment dress.
Summary of the invention
The purpose of the invention is to overcome the intelligent close-fitting sports garment of above-mentioned prior art decorations are existing to measure contact surface
The problem of snugness of fit reduces after product is not complete, measurement data is inaccurate and perspiration, provides a kind of comfortable and easy to wear and measurement data
The movable intelligent close-fitting sports garment decorations of the high reflection skeletal muscle of accuracy.
In order to achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of movable intelligent close-fitting sports garment decorations of reflection skeletal muscle, close-fitting vest of the invention, which focuses on, emphasizes that sports wear is worn
Dai Houyu target skeletal muscle is in close contact, in order to be ensured that monitoring modular can be close to skeletal muscle, and then can be passed through shape
Becoming and reflects skeletal muscle activity condition, contact portion can be not close-fitting with skeletal muscle after sports wear wearing, can also be loose, all exist
In protection scope of the present invention, the movable intelligent close-fitting sports garment decorations of reflection skeletal muscle of the invention include costume ontology, center
Processor and monitoring modular；

MV/cm and cm, a and b be by repeatedly measure in the elastic conductive fiber of known spread length d and thickness t two measurement points it
Between voltage and current after carry out least square fitting and obtain；
Reflect that skeletal muscle activity refers to when the spread length of elastic conductive fiber in continuous time is incremented by, central processing unit
Output skeletal muscle is carrying out contraction movement；When the spread length of elastic conductive fiber in continuous time successively decreases, central processing
Device output skeletal muscle is carrying out diastole activity.
