Abstract
A novel flexible pressure sensor is provided. Most existing pressure sensors are sensitive devices and can accurately detect pressure, but the sensors are greatly limited in the range of application and cannot be applied to soft materials. The novel flexible pressure sensor is composed of two or more than two electrode plates and elastically-deformed dielectric; the elastically-deformed dielectric is clamped between the electrode plates; and the electrode plates and the elastically-deformed dielectric are alternately overlapped, and capacitance changes with borne pressure. The novel flexible pressure sensor of the utility model can be applied to beddings so as to detect human characteristics and has high sensitivity.
Description
Technical field
The present invention relates to a kind of sensor.
Background technology
Pressure transducer is a kind of sensor the most conventional in industrial practice, it is widely used in various industrial automatic control environment, relate to water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, numerous industries such as pipeline, current pressure transducer mostly is Sensitive Apparatus, sensitivity is also very high, can very accurately detect pressure, but these sensors are limited by very large in range of application, can not be applied on soft material, as pillow, mattress, clothes, so can also have certain limitation on reconnaissance range, can not detect constantly human body physiological characteristics changes.
Summary of the invention
A kind of novel elastic pressure transducer, its composition comprises: more than 2 or 2 battery lead plates and the dielectric layer of elastically deformable, between described battery lead plate, accompany described dielectric layer, the dielectric layer of described battery lead plate and described elastically deformable alternately stack is placed, and electric capacity can change with the variation of pressure.
The dielectric layer of described battery lead plate and described elastically deformable alternately stack is rolled into solid tubulose or hollow tubular.
The dielectric layer of described battery lead plate and described elastically deformable is alternately stack placement of tabular.
At least two of described battery lead plates, at least one of the dielectric layer of elastically deformable, and by one group of wire, odd electrode plate is in parallel, another group wire is in parallel by even electrode plate.
Beneficial effect:
The dielectric stack alternative arrangement of battery lead plate of the present invention and elastically deformable, changes with pressure according to capacitance, can detect accurately pressure, highly sensitive;
The present invention adopts the dielectric of battery lead plate and elastically deformable alternately to superpose and be rolled into tubulose, can accurately locate, and avoids because occurring to slide, misplacing and causing pressure detection inaccurate between battery lead plate and the dielectric of elastically deformable;
The material that the present invention uses be there is the elasticity of high elastic modulus can shape-changing material, replaced the pressure detection sensor of hard, can be placed on and in bedding, use and do not affect comfort.
