Great progress in wireless technology

The idea of producing electricity from airborne vibrations is not new, but a team at the Singapore Institute of Science and Technology has turned it into reality. They have just announced that they have found a way to efficiently collect power from low frequency oscillations to power small electronics.

This process takes place thanks to aluminum nitrate , one of the naturally charged materials in reaction to mechanical stress . This is what is called piezoelectric effect .

The achievement of Singaporean scientists is a big step forward. Previously they said that the amount of electricity collected depends on the size of the device and only use one frequency, resulting in low efficiency of electricity production.

The new method allows the use of a wide spectrum of frequencies and performance even in tiny devices, such as wireless sensors.

However, we are not in a hurry yet, as it is far from able to light the bulbs in the house just by sound from the environment. But this technology is very promising, is a big step forward in wireless technology and medical technology.
