Thin-film thermocouple has many excellent characteristics

such as small size

small heat capacity and fast response speed

in recent years

it becomes the focus of research scholars. Common preparation methods for thin-film thermocouple are RF sputtering

ion plating method and DC pulsed magnetron sputtering method

etc.However

these methods are complex to operate

and production time is long and efficiency is low

success rate is low and reproducibility is poor. Electronic printing technology is used to prepare Au-Pt thin film thermocouple.Solubilized gold and platinum materials is printed onto substrate

and then print it to be Au-Pt thin film thermocouple. This method is convenient

and fast for operation and less pollution. Experiments show that

the AuPt thin film thermocouple fabricated by electronic printing technology meets requirements of vertification regulation

precision is high

repeatability and consistency is good.
