Flexible thermoelectric generator and manufacturing method thereof

Abstract

The invention relates to a flexible thermoelectric generator and a manufacturing method thereof, which includes a flexible connector. The flexible connector includes several N-type thermoelectric material bodies and P-type thermoelectric material bodies; one end of the N-type thermoelectric material body passes through a first conductive connection layer One end of the P-type thermoelectric material body adjacent to one side of the N-type thermoelectric material body is electrically connected, and the other end of the N-type thermoelectric material body is adjacent to P on the other side of the N-type thermoelectric material body through a second conductive connection layer. The other end of the thermoelectric material body is electrically connected; the N-type thermoelectric material body and the P-type thermoelectric material body are connected in series through the first conductive connection layer and the second conductive connection layer to form a thermoelectric material body, and the thermoelectric material body is filled with a flexible insulating protective body; The flexible connector is covered with a first insulating protective layer and a second insulating protective layer. The invention has compact structure, simple and convenient process, low manufacturing cost, high power generation efficiency, can be moderately bent, greatly expands the adaptability range of the thermoelectric generator, and is safe and reliable.

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...
