New graphene materials will bring night vision to mobile phones and cars
Many night vision-enabled thermal imaging equipment can help police, search and rescue personnel and soldiers see the surrounding environment in complete darkness, bringing great convenience to combat, rescue and capture operations, but it is the best now. Night vision equipment also requires a process of cryogenic cooling, while the equipment is cumbersome and expensive, and the technology advances slowly.

Recently, researchers from MIT have developed a new graphene semiconductor material that is 100 times harder than steel. Applying this material to a chip in a thermal imaging device can solve the above-mentioned problems. In addition, infrared sensors derived from this new graphene material minimize volume and can even be integrated into smartphones and laptops in the future.
Graphene is one of the most common infrared sensing materials, so MIT's research team uses this material to make sensor chips. Graphene is used to carry signals and to cool in a fixed space, and to get rid of the limitations of external cooling, and these devices can directly dissipate heat internally to improve equipment efficiency.
This compact sensor detects the shape of many objects, including the shape of the hand shown in the image above. The purpose of the current research needs to further improve the resolution of imaging, and it can be applied to devices in daily life in the future. One day, in addition to smartphones, this material can be applied to the front windshield of a car, giving the driver a better view and range at night. However, it is still a long time to wait for the practical application of this graphene material.

WHAT IS AN Air Purifier?
Breathing clean air is very important.
It is scientifically proven that the air in our homes contains allergens(pollen ,mites ,moulds ,etc ).
noxious substance, bacteria viruses and suspended smells.
We have the solution for it!

A clean filter indicator alerts you when the filter needs to be cleaned
Sleep mode
Negative ion
Golbal Patent Technology
Our new technology is still ESP technology,but with non-metallic electrodes,it uses the principle of higher resitivity alloy negative electrode junction plastic ionized air.The higher resistivity is relatively high,the distance between the poles can do much smaller without causing breakdown;with the same volume,it can provide considerable absorption area to increase CADR.
