An alginate hydrogel-based thin-film heat flux sensor for billet crystallizer includes an alginate hydrogel substrate. The alginate hydrogel substrate is configured in a U-shaped planar structure. The U-shaped planar structure includes a first side and a second side, and the first side is longer than the second side. An inner surface of the alginate hydrogel substrate is provided with a first film thermocouple and a second film thermocouple. The first film thermocouple is in crosslinking connection with the second film thermocouple.

A silicon carbide-based micro-electro-mechanical system (MEMS) combined temperature-pressure sensor chip and a preparation thereof. The chip includes a peripheric pressure-measuring unit and a center temperature-measuring unit. The pressure-measuring unit includes a silicon carbide substrate with a raised island and a pressure sensitive diaphragm formed by etching the back of the substrate. The raised island and the pressure-sensitive diaphragm constitute a membrane-island structure. Four piezoresistive strips are arranged symmetrically along a circumferential direction of a root of the pressure-sensitive diaphragm and between the raised island and the pressure-sensitive diaphragm. The temperature-measuring unit includes the raised island and a thin-film thermocouple arranged thereon.

A thin-film thermocouple probe includes a columnar substrate, a tungsten-26% rhenium film and an indium oxide (InO) film. A side surface of the columnar substrate is provided with a first straight groove and a second straight groove. The tungsten-26% rhenium film is arranged on a front end surface of the columnar substrate and in the first straight groove. The indium oxide film is arranged on the front end surface of the columnar substrate and in the second straight groove. The indium oxide film on the front end surface of the columnar substrate is connected to the tungsten-26% rhenium film on the front end surface of the columnar substrate. A first metal lead wire is connected to the tungsten-26% rhenium film, and a second metal lead wire is connected to the indium oxide film. A method of preparing the thin-film thermocouple probe is provided.

The present invention provides a method of on-line rapid fluid density measurement using a piezoresistive micro-cantilever, the present invention can achieve on-line measurement without changing the existing device; more importantly, without acquiring the resonant frequency of the cantilever in fluid to be detected, thus remarkably reducing measurement time, and guaranteeing the real on-line rapid measurement. By using the method of the present invention, measurement of the density of fluid to be detected by a calibrated piezoresistive micro-cantilever may be achieved within seconds or even shorter.
