Description

EXAMPLE 1

[0030] Making the unit cell reference sample by the prototype of the barium titanate. A pattern having a surface area of 1 dm.sup.2 is placed on the polished polytetrafluoroethylene base coat treated with polymethyl and a layer of iron with thickness of 9-10 microns is sprayed. The pattern is removed and another layer of barium titanate is sprayed, providing a continuous uniform non-porous coating with a thickness of up to 1 micron.

[0031] Then the pattern is placed back and a nickel layer with thickness of 9-10 microns is sprayed. The pattern is removed and a finish element is separated from base coat with a vacuum cup. Using diethyl ether polymethylsiloxane traces are removed from the surface layer of iron and the remainder of diethyl ether is removed by blowing dry air. Then the unit cell is placed between binding posts made of iron and nickel respectively. Obtained electrical power generator is connected to a power source.

EXAMPLE 2

[0032] Making a unit cell of barium titanate doped with niobium.

[0033] The unit cell is made by means of the technique described in Example 1, werein instead of barium titanate barium titanate doped with niobium is used.

EXAMPLE 3

[0034] The unit cell is made by means of the technique described in Example 1, werein instead of barium titanate barium titanate doped with lanthanum is used.

[0035] Table 1 shows the relationship between electric power (mW) and values of voltage (V) and electric current (mA) of one unit cell at external load of 1000 Ohm from ferroelectric materials semiconductors relatively to reference sample by prototype made of barium titanate.

[0036] We studied the duration of work of each of the ferroelectric-semiconductor, which is part of a single unit cell. In the temperature range from ?20 to +110 degrees Celsius each unit cell is continuously operated for more than 18000 hours.

[0037] As it can be seen according to the table, in case of using ferroelectric semiconductors electrical power increases dramatically. When barium titanate doped with niobium (Nb) is used electrical power of the generator unit cell increases by 2,088 times relative to the prototype. When barium titanate doped with lanthanum (La) is used electrical power of the generator unit cell increases by 1,869 times with respect to the prototype. The claimed power generator has a significant advantage over the prototype according to its practical application.
