Abstract

The invention relates to a flexible thermoelectric generator and a manufacturing method thereof. According to the technical scheme provided by the invention, the flexible thermoelectric generator comprises a first flexible substrate and a second flexible substrate located under the first flexible substrate, wherein a plurality of N type thermoelectric material particles and P type thermoelectric material particles, which are alternately distributed, are arranged between the first flexible substrate and the second flexible substrate; the N type thermoelectric material particles are electrically connected with the P type thermoelectric material particles in series through a first electrical connection layer on the first flexible substrate and a second electrical connection layer on the second flexible substrate, so that a plurality of thermoelectricity paired thermoelectric materials is formed between the first flexible substrate and the second flexible substrate; and the thermoelectric materials are packaged between the first flexible substrate and the second flexible substrate through flexible insulation and thermal insulation encapsulating materials. The flexible thermoelectric generator has a simple and convenient process, low manufacturing cost, high generating efficiency, and capability of being bent moderately, the application range is broadened, and the safety and the reliability are realized.

Description

technical field [0001] The invention relates to a thermoelectric generator, in particular to a flexible thermoelectric generator and a manufacturing method thereof, belonging to the technical field of thermoelectric generators. Background technique [0002] Due to the growing miniaturization trend of portable electronic products, the research and development of miniaturized power supplies are promoted. As a self-sufficient energy source, thermoelectric generators can directly convert heat energy into electrical energy according to the Seebeck effect, and can maintain a practically unlimited effective life at a suitable temperature, which makes it a high-tech in the energy field. One of the hot spots of international research. [0003] A thermoelectric generator generally consists of three parts: a heat source, a heat sink, and a thermopile. A thermopile is a series of thermoelectric pairs connected in series that convert heat energy into electricity (Figure 2). A thermoel...
