Title:
FUNCTIONAL ELEMENT HAVING CELL SERIAL STRUCTURE OF π-TYPE THERMOELECTRIC CONVERSION ELEMENTS, AND METHOD FOR FABRICATING SAME
Document Type and Number:
WIPO Patent Application WO/2018/047882
Kind Code:
A1
Abstract:
Provided is a functional element resistant to disconnection, comprising a structure for obtaining a flexible thermoelectric device with a sufficient thickness for obtaining a temperature difference, the structure having a textile structure in which threads configured from thermoelectric material are stitched into a flexible insulating base material having a small thermal conductivity. In an element structure, a plurality of serial structures of π-type thermoelectric conversion cells that utilize a temperature difference in the thickness direction of an insulating base material are arranged in parallel, the element structure having a topology in which, at portions where p-type and n-type are switched, stages that have the same potential during electric power generation are electrically connected, wherein the π-type thermoelectric conversion cells are connected as electric circuits both lengthwise and widthwise in a mesh via serial connection and parallel connection. In this way, a functional element can be provided that is not susceptible to deterioration in output characteristics due to disconnection. Specifically, an n-type spun yarn and a p-type spun yarn comprising an electrically conductive fibrous substance are stitched into a sheet of insulating base material alternately and in parallel, wherein the n-type spun yarn and the p-type spun yarn are electrically connected when respectively alternately penetrating through a front surface and a back surface of the insulating base material.
