Evaluation of thickness‐dependent temperature coefficient in a thin film thermocouple and its in vivo test using a porcine model
A micromachined thin film thermocouple (TFTC), that is, a contact-type temperature sensor, was fabricated to diagnose the physiological state. The TFTC involved two metal films (copper and constantan) with considerably different Seebeck coefficients. Six types of TFTCs with different film thickness values were fabricated and experimentally characterized to determine the thickness-dependent temperature coefficient attesting to a high sensitivity of the sensors. The performance of each TFTC was evaluated by measuring the induced thermal electric motive force and temperature in the temporal and spatial domains by using a data acquisition board and an infrared camera, respectively. Moreover, an in vivo experiment of the proposed TFTC with the highest temperature coefficient (38.9 µV/°C) was conducted by measuring the body temperature difference of an anesthetized porcine model during its euthanasia process to evaluate the device performance.
期刊介绍：
The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites.
The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
