A high-temperature sensor based on a metamaterial unit cell is proposed in this paper. The wireless passive temperature sensing method the electromagnetic backscatter principle, and thus has advantages of higher quality, lower environmental interference, anti-low frequency interference. We developed finite-element method-based model for via high-frequency simulation software (HFSS). double split-ring resonator (SRR) with an outer ring length 13 mm was designed alumina ceramic substrate....
This paper presents a new wireless sensor structure based on substrate integrated circular waveguide (SICW) for the temperature test in harsh environments. The material is 99% alumina ceramic, and SICW composed of upper lower metal plates series cylindrical sidewall vias. A rectangular aperture antenna surface resonator used electromagnetic wave transmission between external antenna. resonant frequency decreases when increases, because relative permittivity ceramic increases with...

In order to identify suitable substrate materials for sue in high‐temperature pressure sensors that can operate above 1000°C, the properties of four high‐performance ceramics (99% pure Al 2 O 3 (99Al ), 97% (97Al sapphire, and ZrO ) were investigated. Three‐point bend testing was used measure flexural strengths moduli these ceramics, transient laser emission their thermal conductivities. The samples prepared by hot‐press sintering: plates with dimensions 3.5 × 5 50 mm rods φ 12.5 1.5...
Purpose This paper aims to present a novel wireless passive pressure sensor based on an aperture coupled microstrip patch antenna embedded with air cavity for measurement. Design/methodology/approach In this paper, the sensitive membrane deformed when was applied surface of and relative permittivity mixed substrate changed, resulting in change center frequency antenna. The size is determined by theoretical calculation software simulation. Then, fabricated separately as three layers using...
We reported that alpha-ketoglutarate (α-KG) is indispensable for chronic hypoxia (CH)-induced cardiac remodeling, which builds the bridge between metabolic intermediates and remodeling.
