Flexible temperature sensors

Thin Thermocouples


Our thin thermocouples were created by combining heat-resistant film with thin films.
They can be customized with different shapes, measurement point locations, and numbers of units, depending on what you want to measure.

Features & Strengths

Point1 Slight thickness achieved by using film as a base material

The thermocouples are formed using 7.5 μm thin films as the base film material. They are ultra thin, measuring a total of 12 μm.

Point2 Made smaller using fine processing technology, they can be used to measure temperatures in narrow or complex areas Measurement capability

They make it possible to measure temperatures in tiny openings, inside machines, or in high pressure environments.

Point3 Flexible layout

They can be designed according to the desired shape of elements, measurement locations, or targets to be measured.

Point4 High response rate

Since they are low in heat capacity, they can respond quickly to changes in temperature.


Temperature measurement of electronic parts

Measure temperatures, even in tight gaps or intricate spaces

Measure temperature of heated rollers

The temperature of heated rollers can be measured directly when crimped.


Manufacturing examples

The thermocouples can be produced with elements shaped as needed, such as multi-point measurement, thermopile, and the target of direct measurement.
