Researchers from the National Research Nuclear University MEPhI (Russia) are developing radio isotope beta-voltaic batteries with nickel-63 nano-cluster radio isotope films. The concept is to develop safe nuclear batteries with a service life of 100 years for pacemakers, miniature glucose sensors, arterial blood pressure monitoring systems, and for controlling remote objects and micro-robots, and self-contained systems that can operate for a long time. Research results are published in the journal Applied Physics Letters.

Researchers are more interested than ever in projects to develop nanotech to miniaturize technological devices, primarily nano-electronic systems. The latest achievements in creating micro-electromechanical and nano-electromechanical systems that combine nano-electronics and mechanical elements can make it possible to develop microscopic physical, biological or chemical sensors. However, the lack of miniature batteries for powering micro-electromechanical and nano-electromechanical systems hampers the large-scale introduction of such devices.

Today - Scientists - Possibility - Miniature - Lithium-ion

Today, scientists are studying the possibility of creating miniature lithium-ion batteries, solar panels, fuel cells and various types of condensers. However, these batteries are still too large for developing truly microscopic and nano-sized systems.

Another approach to powering advanced micro-electromechanical and nano-electromechanical systems is the use of radio isotope batteries. radio isotope or nuclear or atomic batteries convert the energy of radioactive decay of meta-stable elements (atomic nuclei) into electricity. These elements have high energy density levels for their mass and volume. The duration of sustained energy emission varies, depending on the choice of nuclides. Silent radio isotope batteries can operate without an error or maintenance for a long time.

Conversion - Methods - Energy - Decay - Electricity

Thermo-electric conversion is seen as one of the most convenient methods for converting the energy of radioactive decay into electricity. But scientists are also studying beta-voltaic batteries and their practical applications. By installing a radio isotope that emits soft beta radiation in a miniature battery, it is possible to shield users and nearby objects from radiation. Therefore,...
