Electronics Gadget

Recently, scientists have to demonstrate the size of a coin micro "fuel cell." The battery using the decay of radioactive elements in the same position to generate energy.

The researchers introduced the decay of radioactive substances, it will release of charged particles, if these particles can be collected, will be able to generate electricity. In fact, because the nuclear Dell Latitude D410 battery， Dell Latitude D500 batterybattery energy storage quite rich (its content is the general standard battery charge of 1 million times), a long time ago had been in military and aerospace fields to be applied, but these nuclear batteries than the block header to show nuclear battery. University of Missouri research team invented the这枚pocket-sized fuel cell.

The reason why the university's development of micro fuel cell is aimed at reducing the size of electronic devices inside the power supply, making it more suitable for small devices (such as micro-electromechanical systems or nano-electromechanical systems), because such equipment itself is small enough, there must be a smaller power supply matched. Therefore, the development of micro-power and development of micro-motor itself is just as important.

For a lot of equipment, fuel cells are quite attractive, because radioactive isotopes can provide them with a powerful stream of electricity, and they are extremely durable, the use of deadlines are generally up to several hundred years or even longer. Thus, in space exploration, fuel cells have become the ideal choice. However, in the earth, because the volume is too large, yet they could be a fuel cell the ability to full play.
University of Missouri research team set out from the right of 10000 (Jae Wan Kwon), led by Professor. The course of their study using a liquid semiconductor to capture and use the decay of charged particles. In contrast, most of the available fuel cells are used in solid-state semiconductors. The latter disadvantage is that the energy contained in the charge decay is extremely rich, solid-state semiconductors over time will have some damage. This means that if you want to create the same battery life with the radioisotope, it must be placed in the battery as much as possible within the solid-state semiconductors. As a result, the greater the volume of the battery.

The rights are set, Professor reason they use liquidDell Latitude D600 battery， Dell Latitude D610 battery semiconductors, because the high-energy electric charge through the liquid semiconductors will not cause harm to it, so can greatly save the semiconductor space occupied. Currently, researchers are working to further the battery a "mini-oriented."

In order to dispel people's concerns about the safety of nuclear fuel, the researchers explained that although the success of the entire battery depends on whether the use of radioactive substances, but in normal working conditions, use is completely safe. Of the right says: "Most people are scared at the mention of nuclear talks, and believe that anyone associated with the nuclear stuff would be very dangerous. But we must not overlook the fact that many devices have been safe and successful application of nuclear energy, such as pacemakers, space satellites, underwater operating system. "
