Title:
TEMPERATURE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/067753
Kind Code:
A1
Abstract:
This temperature measuring device comprises: a thermal conductor (10) which is disposed such that a peripheral part thereof contacts a living body (100), which has anisotropic thermal conduction such that thermal conductivity in the in-plane direction is higher than thermal conductivity in the thickness direction, and which is flexible; a thermal insulation material (11) which is disposed so as to fill a space between the living body (100) and the thermal conductor (10), and which is flexible; sensors (12, 13) which measure the degree of heat flow conducted from the living body (100); a thermal insulation material (14) which is disposed so as to cover the thermal conductor (10) and which is flexible; and an electronic circuit unit (2) which calculates the internal temperature of the living body (100) on the basis of the measured degree of the heat flow.
