The piece of piezoelectric material bonded to the top of the silicon cantilever bends along with it. This has been tested experimentally. Need for compact, reliable, light weight and long life power supplies.

One is junction type battery and the other is self-reciprocating cantilever. Nuclear batteries have lifespan up to decades. Batteries of the near future. Scientists have developed two types of micro nuclear batteries. Nuclear pestel ppt 2 Documents. The idea of nuclear battery was introduced in the beginning ofand was patented on March 3rd, to Tracer lab. Published on Apr View Download 7. These electrons get collected on the copper sheet.

Any radioisotope in the form of a solid that gives off alpha or beta particles can be utilized in the nuclear battery. New microbatteries a boost for electronics. High power for long time independent of atmospheric conditions. So the self-reciprocating cantilever type nuclear batteries are also called as radioactive piezoelectric generator.

Daintiest dynamos [nuclear microbatteries Documents. Radiations Alpha – These are fast moving helium atoms. To gain social acceptance. Automobiles No need for frequent recharging as in case of present electric vehicles.

Somatic cell nuclear transfer ppt Technology. This process will repeat as long as the source is active. Since it is not easy to micro fabricate solid radioactive materials, a liquid source is used instead for the micro machined p-n junction battery.

As shown in figure a number of bulk-etched channels have been Micro machined in this p-n junction. The cantilever then springs back and oscillates like a diving board after a diver jumps, and the recurring mechanical deformation of the piezoelectric plate produces a series of electric pulses.

They have succeeded by developing nuclear batteries. It is similar to the mechanics of converting sunlight into electricity in a solar panel. The emitted beta particles ionized the diode’s atoms, exciting unpaired electrons and holes that are separated at the vicinity of the p-n interface. Nuclear batteries use the incredible amount of energy released naturally by tiny bits of radio active material without any fission or fusion taking place inside the battery.

The concerned p-n junction has 13 micro machine channels and the total junction area is Until final disposal all Radiation Protection Standards must be met.

Energy Production Mechanism 5. The operations of both are explained below one by one. The diagram of a micrlbatteries machined p-n junction is shown below. Compared with planar p-n Junctions, the three dimensional structure of our device allows for a substantial increase of the junction area rynamos the macro machined channels can be used to store the liquid source. Beta particles emitted by radioactive gas is captured in Silicon wafer coated with diode material.

All these difficulties can be overcome up to a large extend by the use of nuclear micro batteries. These dynamo use thin radioactive films that pack in energy at densities thousands of times greater than those of lithium-ion batteries.

Radioisotope thermo electric generators RTGs exploited the extraordinary potential of radioactive materials for generating electricity.

PPT on Nuclear Microbatteries

Others are developing on-chip combustion engines, which actually burn a fuel like gasoline to drive a minuscule electric generator.

It consists of a core composed of radioactive elements. Uses energy from beta particles. A ppt on natural disaster and safty risks at nuclear power plant Environment. Batteries should have reliability and longevity to avoid frequent replacements. On this cantilever beam there is a copper sheet attached to it.

Reduces green house and associated effectsFuel used is the nuclear waste from nuclear fission. Are you interested in this topic.

Copper sheet becomes negatively charged. Can be used in extreme conditions and reduce the rate of replacements. Also dhnamos this cantilever there is a piezoelectric plate. A radio isotope electric power system was developed by inventor Paul Brown which was a scientific break through in nuclear power.

They typically have energies in the range of a few hundred keV to several MeV.

This is very important since the current generated by the powered p-n junction is proportional to the junction area. NASA is trying to harness this technology in space applications.

The discharge can also take place through tunneling or gas breakdown.
