The ultra-small electronic devices are often installed in locations difficult to access. In addition, access may also influence their activity and therefore, the equipment must be designed to limit the replacement battery during use. Recently, the Canadian company City Labs has announced the commercial release NanoTritium - betavoltaic a battery the size of thumb with the ability to absorb energy emitted by radioactive elements to provide more nW (nanoWatt) to the island uninterruptible power protection operation time of more than 20 years. The world still exists about 11 kg of tritium (a radioactive isotope of hydrogen). Although only present in upper atmosphere in nature, tritium can be produced in commercial nuclear reactors and is used in products such as self-illuminating the indicator on your table fly, luminescent paint, road signs and wristwatches. It is also considered a good betavoltaic sources, providing low-energy electron current continuity and stability for many years. According to the Environmental Protection Agency (EPA) regulations, tritium decays with half of 12.3 years and the battery version P100a NanoTritium Model developed by the City Labs is said to be able to provide power for electrical equipment micro-sensor element and more than 20 years. Power was described as very stable and closed with tritium-preserved integrated solid form. Testing done by Lockheed Martin in a survey shows that the technology industry with high heat resistance (-50 ° C to 150 ° C) and resistant to vibration and altitude. The possible applications for the technology provided by the City Labs including the temperature sensor / pressure environment, smart sensors, implantable medical devices, the extra charges for lithium batteries, the RFID tag sale passive and active, space probes, watches semiconductor memory backup SRAM, probes deep-sea oil wells cavity and the low-power processor. City Labs, said the company has licensed Regulatory Product General License to manufacture, sell and distribute products NanoTritium pin. Thereby, P100a pin version is the first energy betavoltaic to ordinary users - those who are not licensed to use radioactive energy and has not been approved by the authorities or through the special training. Denset Serralta, co-founder of City Labs has confirmed that the battery has started NanoTritium is offered and price range will be approximately $ 1,000. However, the price will decrease or remain unchanged at increased energy output in the future. City Labs is a company co-founder of Alienware - backed Alex Aguila, currently under Carrie Meek Business Center NASA-funded Center in Homestead, Florida and is a pioneer in technology betavoltaic - Larry Olsen held research director. The company said betavoltaic generation of higher energy batteries are being developed and we can supply 10 μW (microwatts) in a long time or intermittent mW (milliwatts). Betavoltaic is the form of battery power, using energy from radioactive sources emit beta particles (electrons). One common source used is the isotope of hydrogen - tritium. Unlike other nuclear energy, which use nuclear radiation to generate heat and then converted into electricity, betavoltaic not use metabolic processes nhieejtl conversion electron-hole pairs produced by the ion beta chains of particles passing through a semiconductor. Betavoltaic energy sources particularly suitable for use in applications that require low power but require long battery life, such as implanted medical devices or applications in military and space.
