Lginnotek, a subsidiary of lg Group's mobile device group, recently announced that it has developed an ultra-small heart rate sensor module that can be used in a wide range of wearable devices and smartphones. In the new heart rate sensor, lg incorporates image diodes, light-emitting diodes and semiconductor chips, the thickness of a single module is only 1 mm thinner than the coins. When new sensors are applied to wearable devices and smartphones, the design can be made lighter and more free. Compared to the existing modules, the new sensor has a 30% increase in live signal reception and a 20% reduction in energy consumption. Fpc, a biometrics development company, has successfully developed a new fingerprint sensor prototype called "fpc1268" that can be placed under a cellphone cover glass with a thickness of 300 microns. The sensor is also compatible with toughened glass, which is currently widely used in smart phones, play a fall protection. There is also a new fingerprint sensor, it is small enough to fit into the volume keys. The new mobile fingerprint sensor from synaptics, which measures only 3.5mm in width and can be placed in volume keys on the side of smartphones and tablets. In addition to being lighter, thinner and smaller, the sensor can morph into a "surface." Earlier, there are rumors that Apple's spherical surface sensor patents will be used in the next generation of Apple's mobile phone. According to the patent description, this patent is a spherical image sensor to be used in a compact camera module. Due to the omission of steps to correct the curvature of field, this sensor makes the entire lens module design simpler and achieves a larger aperture with a smaller lens size. The benefits of using surface sensors are to make the design of the entire lens module simpler. The lens module will contain only three lenses. Reducing the number of lenses will also reduce the incidence of light and provide sharper photos. Mobile phone sensor to a lighter and thinner smaller direction
Fluid Steel Pipe are pipes specially used for conveying media with fluid properties.

Medium with fluid properties, in addition to liquid media such as water, oil, and solution, solid media such as cement, grain, and coal powder can also flow under certain conditions.
The fluid pipe must have a hollow cross-section, and it can also be square, triangular or any other shape. Some equipment is restricted by conditions, and rectangular pipes must be used, but most still use round pipes. The round tube has the smallest perimeter/area ratio in all geometric sections, that is, the largest internal section can be obtained under the same amount of material.
Steel pipes are also an indispensable material for various conventional weapons. Gun barrels and barrels are all made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Because the circle area is the largest under the condition of equal circumference, the circular pipe can transport more fluids, and is widely used to transport oil, natural gas, gas, water and certain solid materials.
