Santorini is cut off communication during an important call via mobile phone due
to power outages of the battery, and the need to be recharged, for example, or
going to discover too late that has missed an important appointment, because the
hour hand has suddenly stopped working. But is it possible to imagine doing
connections through a mobile phone without the need for a battery, only
depending on the temperature of the body? This idea may seem closer to science
fiction, but it may turn into reality, after that, a group of scientists from
the German Fraunhofer Institute to reach a new method to convert body heat into
electric current.
Is a scientific principle and applications of new
This technique depends on the principle of scientific known since 1821, discovered the world of nature the German Thomas Sepik, also confirmed Peter Hbas, one of the researchers involved the project, said in an interview for our website, saying: "The principle has been known for a time, a so-called born Alkahrouhrrari, who works at the the impact of the so-called Sepik, or influence Alkahrouhrrari. by this generator can convert between degrees temperature difference between the two objects to different electrical energy, or to the difference voltage. We have developed new circuits can be turned this small difference in voltage potential difference to a large , that is, to a large electric current, can be relied upon to run electronic devices known.

The body's energy instead of batteries
Bildunterschrift: Großansicht des Bildes mit der Bildunterschrift: Is it possible to dispense with batteries in the future? There is already a demo of this technology at the Fraunhofer Institute, where one can put his hand on the device that generates a quantity of energy sufficient to power sensors temperature and to send information wirelessly, and there are some practical applications that have been in the industrial field, but so far limited, and in this framework, Hbas says: "It's about, of course, the efficiency of circuits used. At the moment, still the energy that can be gained from the heat of the body is limited, for example, enough to run a watch, or a device to measure the pulse, or things like that."
Technique can serve the patients lying on their beds in intensive care, and Mahatin wire from each side, as these devices powered by electricity to measure blood pressure or heart rate or body temperature, can be replaced devices are plugged in electric generator of the human body itself, as can send the information on these devices wirelessly to the control unit of the medical doctor or therapist.
The recipient's phone - Does it work without a battery?
Bildunterschrift: Großansicht des Bildes mit der Bildunterschrift: in the distant future, may be running a mobile phone without the need for batteries ... And applications of this technology, although still limited so far because of the small amount of energy that can be generated, but taking into account the developments that occur on the circuit, which makes them more efficient, you can imagine that using this technique in a larger number of systems. Which is confirmed by Hbas saying that in the near future can be dispensed with completely imagine the batteries in some of the hardware or the need for shipped at a lower rate.
Among the devices that can be in the future to rely on that technology, mobile device, though this is in the opinion of Hbas still a distant dream, where he says: "It's difficult with mobile phones, because they need so far to a large amount of energy to run, but Thanks to technological development in manufacturing, which serves to reduce the amount of energy required to run them significantly, it can be to imagine that this is achieved in the distant future.
