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.

Provided herein is a tungsten-rhenium composite thin film thermocouple based on a surface micropillar array with gas holes. A tungsten-rhenium thin film thermocouple is arranged on a surface of a flat alumina ceramic substrate. Two tails of the tungsten-rhenium thin film thermocouple are respectively connected to a lead wire. A surface of the tungsten-rhenium thin film thermocouple is arrayed with a plurality of micron alumina micropillars to form an alumina micropillar array. Air is filled between the micron alumina micropillars to form the gas holes. The flat alumina ceramic substrate, the tungsten-rhenium thin film thermocouple and the alumina micropillar array form a three-layered laminated structure.

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.
