50 Best Inventions In 2009 (Two)

8. AIDS vaccine

Strictly speaking, the vaccine is no longer an innovative invention.

However, the joint vaccine developed by researchers in the United States and Thailand is a leap forward innovation.

Research shows that this joint vaccine can reduce the risk of human infection with HIV by 31%.

This is the first time that human beings have acquired an AIDS vaccine with immune effect.

9. think and turn into words.

Adam Wilson, from University of Wisconsin at Madison, looks a little different.

He and his team designed a brain wave analysis hat and linked it to the social networking site twitter on the computer, so that people could send out the words in their heads through the form of brain waves.

It is learnt that when users put on their caps and connect them to the computer, a row of English letters will appear on the screen.

The emergence of this major invention provides a possibility for people with paralysis of the body to communicate with the outside world.

10. electronic eye

MIT researchers have developed a microchip that allows blind people to regain some of their eyesight.

This chip can at least allow blind people to distinguish themselves from other people's faces and allow themselves to act more freely in the room.

It is reported that the microchip will be implanted into the eyeball of the patient, and the outer layer of the microchip is coated with titanium alloy to prevent water failure.

When the microchip is implanted into the eyeball, the patient still needs to wear a pair of glasses with miniature cameras installed.

Then, the glasses will pmit the image directly to the microchip, and the microchip will pmit the information to the patient's brain.

11. mercury Exploration Tour

According to scientists, the temperature of mercury is as high as 426 degrees C.

Because of the high temperature, NASA is unable to explore the planet.

However, the mercury probe "messenger" can tolerate such a high temperature.

It is reported that the "messenger" can withstand the high temperature of up to 370 degrees C outside, and inside the detector, the temperature is controlled at 20 degrees C.

12. people's carbon footprint

Whether it is developed countries like the US or developing countries like China, it seems that actions on emission reduction are far from enough.

As a result, researchers from Princeton University suggested that efforts should be made to study individual carbon footprint.

Through this study, researchers hope to find out the real reason for reducing emissions.

13. solar roof tiles

Dow Chemical has developed a solar roofing tile.

It is reported that this solar roof tile generates two times the energy of solar panels.

It is reported that this revolutionary roof tile is expected to cost 10% to 15% less than that of ordinary solar panels.

In addition, the installation cost is lower, and the installation process is quite convenient.

14. portable stethoscope

The stethoscope that really belongs to twenty-first Century may have been published.

In October 20th, Ge Corp launched the smallest B Ultrasound vscan, which looks more like a mobile phone or a small multimedia player.

Such a small volume is very convenient for doctors to carry, and it is also good news for the patients.
