Title:
π型熱電変換素子のセル直列構造を有する機能性素子とその作製方法
Document Type and Number:
Japanese Patent JP6974854
Kind Code:
B2
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.
