...Nowadays, research team is trying to use multiple radio wave energy to low-power miniature devices. With this technique, Duke University has developed a sound reminder alarms with new era caps.
Electronic equipment using radio waves to power early in fact, this idea had been proposed, because the energy in the process of transmission will quickly decay, a long time have been little interest in the technology, but with the silicon technology advances, the more An increasing number of researchers have begun to get involved in this area.
Duke University Assistant Professor of Electrical and Computer Engineering, Georgia Institute of Technology Matt Reynolds and Civil and Environmental Engineering Assistant Professor Yue Hengtai they developed a policy to install the sensors and the helmet as the buzzer "smart hat." Low-power sensor cap can be installed by monitoring the signal strength to determine the location and whether the person wearing a hat is approaching dangerous.
 When workers in the hat near dangerous equipment on the construction site, the cap will automatically sound the alarm. The "smart cap" is unusual in that the electronic equipment installed on it goodbye to the battery installed in excavators and bulldozers at the top of the wireless network has become the wave transmitter power of the air it gets the energy. These launchers were originally designed for tracking the location of bulldozers and excavators.
Powercast in Pittsburgh for the low-power companies are also selling similar equipment at radio wave transmitter and receiver. The company recently introduced a charge for wireless sensor wireless receiver. Central office automatic air conditioning system for monitoring the indoor temperature sensor can be achieved with this receiver is wireless power.
Intel Corporation Research Center, Seattle's chief engineer, Joshua Smith, professor at the University of Washington study also electromagnetic radiation, and has developed an electronic collector, you can capture radio waves around it. The e-collector from the laboratory to 2.5 meters from the TV stations to collect enough energy for a temperature and humidity sensor power supply.
According to Department of Electronic Engineering, University of Washington assistant professor of Black Enao Atlantis, currently in the field of energy saving electronic devices there are two main research directions, in addition to energy from the environment to obtain the research, there are many studies on ways to significantly reduce equipment energy to tackle the problems.
 When the two classes men "successfully joined forces", it is difficult to imagine how many around us will get rid of electronic equipment, batteries, to achieve the air "catch" electricity.
