Description of the Invention: [Technical Field] The present invention relates to a flexible thermoelectric energy converter and a method for manufacturing the same, and particularly to an n-type bismuth telluride (BizTe3) alloy and p_type (SbsTe3) A flexible thermoelectric energy converter in which a p/n thermoelectric film formed by alloy deposition is bonded to a gel structure and a process method thereof. [Prior Art] # In the 19th century, German physicists discovered the thermoelectric effect and opened up research on thermoelectric materials. Lan Nian, with the cooperation of semiconductor technology, the thermoelectric energy converter came out. The thermoelectric energy converter is a main fixture that converts thermal energy and electrical energy. It can generate electricity by using the temperature difference, and the voltage difference can be used to generate temperature difference. In the world of energy consumption, the energy consumption of the world is increasing by 2%, and the price of energy such as natural gas continues to soar, showing the shortage of energy on the earth. In the era of rapid changes, with the advancement and development of science and technology, the demand for energy is increasing, and the utilization and conversion of various energy sources has become the primary issue today. The thermoelectric energy converter has long been recognized by NASA as the main source of power for the 20 space exploration missions, and has been generating electricity from a number of thermoelectric generators that use (four) sub-energy fuel as a heat source. The source, the heat source of the ground and the μ live material are “the heat energy brought by the shot is still unable to be effectively recovered and benefited 201126779. The use efficiency of the source of the Fuyue b source is low and waste, and the recycling of various waste heats. The use and utilization not only can improve the conversion efficiency of various energy sources, but also reduce and reduce various thermal pollutions generated in the living environment. Therefore, in the future environmental protection and energy considerations, research and research on energy utilization is particularly important. With the continuous advancement of semiconductor process technology, high-tech electronic products have evolved into high-speed, high-frequency, high-power, and continue to evolve into thin, light and short. In contrast, electronic components are prone to generate enormous thermal power and operate in high-temperature environments. Affect the transfer function of sfl number, and reduce the service life of components. Therefore, how to solve the performance reduction caused by the heat source derived from electronic components and reduce the life of the system has become one of the main focuses of heat dissipation research. Cold and water-cooled heat sinks are still popular, but air-cooled heat sinks have a lifetime Sound and other issues; as for the large size, high price and pollution of water-cooled heat sinks, it is also criticized. Therefore, how to dissipate heat quickly under limited conditions has become a major focus of current technology development. Considering the thermoelectric energy converter, its advantages make it gradually have the tendency to replace the traditional heat sink. The advantages of the thermoelectric energy converter are as follows: 1. Small size and light weight: the volume and weight of the thermoelectric energy converter Smaller and lighter than traditional cooling or heating machinery. 2. No noise, long life, no influence on gravity and direction: General thermoelectric energy converter energy conversion side 4 does not need #传循环传", so its Not affected by gravity and direction, it also reduces the noise caused by pumping required by fluid circulation and the mechanical failure rate of 201126779. 3. Suitable for local cooling or heating. The thermoelectric energy converter can cool or heat the specific component or specific area. Without having to package the whole package around. 4. The same component has various functions such as cooling or heating and power generation: thermoelectric energy converter when input The opposite current, the reverse flow of the semiconductor carrier', the opposite direction of the heat flow, that is, the exchange of cold and hot ends, is also easier to control the temperature; in addition, when the heating energy converter has a certain temperature difference, it will output a certain amount of energy, which can be used as The purpose of power generation or temperature sensing. In addition, it has the advantages of high precision, fast response speed and environmental protection. With the above advantages, the effects of thermoelectricity and other effects have gradually attracted everyone’s discussion, and this kind of related research has gradually matured. It can be seen that there are still many shortcomings in the above-mentioned methods of use, which are not the designers of goodness, but need to be improved.
