Background and Benefits

Summary:

• We show a device and method for temperature sensor.

• The technology is a textile-based temperature thermocouple

device, which provides location resolved temperature

measurements.

• This technology allows temperature measurement in hospitals, bed

lines, garments and houses.

• The textile-based temperature sensing device is flexible,

stretchable, easily adaptable to any measuring surfaces and a

constant temperature coefficient permits calibration and design of

device.2

Textile thermocouple : “has thermoelectrodes

that are manufactured from textile structures such

as threads, yarns, fibers, twisted of non-twisted

multifilaments, woven, knitted and non-woven

fabrics. Fibers used to manufactured the textile

structures can be of electroconductive polymers

fibers with electroconductive nanoparticles inserted

in the polymer matrix and fibers with surface coated

by an electroconductive material. ” Ziegler et.al.

Our suggestion: “ A textile thermocouple is a

a conductive textile matrix, which is less a carrier

textile but an indispensable unit without which the operation of temperature sensor is not possible. ”

conditions of textile thermocouples, Fibres Text. East. Eur. 77 (2009) 84–88.
