The United States Virginia commonwealth university scientists have announced that they developed a maybe the lowest energy consumption of the integrated circuit. This circuit for energy is few, even have no need to install the battery, from the surrounding environment of the gain of energy is already enough trace maintain operation. The researchers say, this technology is expected to be implantable medical equipment, buoy and environmental testing and other fields play an important role. Related study, published in the American journal of applied physics letters. This circuit used is called a "more TieXing materials" special composite material, by piezoelectric materials and magnetostrictive nanometer magnet composition. The structure of the material to the mechanical energy or vibration environment into required for the operation of energy, so as to realize the function of the electricity from the environment take. In data storage and transmission, and use through and cut off to show 0 and 1 traditional circuit of different, the integrated circuit using spintronics electron spin in the two states to represent the binary of the two basic code. Therefore, the whole process of switching the equipment only need a very small energy. The researchers say, because these special material selection, the whole circuit for energy only 0.4 o joule (1 o joule = 10 to 18 joule), the Numbers than traditional transistors to small four orders of magnitude. This design can create low power consumption, high density, as nonvolatile memory and logic chip. This technology in many fields has potential applications in medical equipment, such as describing its use in, can save battery module, from the body movement of patients can get energy; This technology can also be used in the sea, and the sea waves in the computer of the buoy will is the constant flow of energy sources. In addition, by the technology of the processor made also applied to manufacture used to detect building or bridge state of sensors, the natural vibration building or Bridges or traffic can provide the energy.
