“…Our research group has worked on CMOS capacitive sensors operating in the frequency range of 5 GHz to 30 GHz for biological purposes [ 59 , 61 , 62 , 63 , 64 , 65 , 66 , 67 ]. The sensing principle is based on the variation of capacitance embedded in a CMOS oscillator, causing a shift in the resonant frequency of the oscillator.…”

“…Another CMOS frequency shift oscillator based approach for biosensing was shown in the works of our group [ 64 , 65 , 66 ]. The sensor is a transmission line configured as an open or a shunt stub [ 29 ], and the oscillator topology is different as well, when compared to the above examples.…”

“…These sensors were also explored to distinguish between two biological targets, like fat and calcium. The results of the sensor approach [ 66 ] operating at 30 GHz is shown in Figure 13 . Such a sensor is proposed to be used as the first screening sensor for detection of plaque (calcified fat) in human arteries.…”

In this paper we review the advancement of passive and integrated microwave biosensors. The interaction of microwave with biological material is discussed in this paper. Passive microwave biosensors are microwave structures, which are fabricated on a substrate and are used for sensing biological materials. On the other hand, integrated biosensors are microwave structures fabricated in standard semiconductor technology platform (CMOS or BiCMOS). The CMOS or BiCMOS sensor technology offers a more compact sensing approach which has the potential in the future for point of care testing systems. Various applications of the passive and the integrated sensors have been discussed in this review paper.

“…Although these technologies are very precise, they are complicated to operate and consume a large amount of sample [7]. Recently, because a substance can be characterized by its unique permittivity, a new technology, based on the dielectric characterization and perturbation theory [8], have aroused considerable enthusiasm and shows great potential in the areas of chemicals [9,10], agriculture [11,12], and biomedical [13][14][15]. As one of the typical representatives of this technology, meta-surface-inspired sensor is a potential candidate for detecting the type and quality of edible oils as it has been applied to successfully detect liquid chemicals [16][17][18], engine lubricant [19], transformer oil [20], edible oil [12,21], and fuel [22].…”

In this paper, a sensor based on a meta-surface absorber loaded with microfluidics is proposed for identification of edible oil species and provides a non-destructive, rapid, and convenient technology for the measured samples. First, a narrow-band absorber with absorption frequency of 9.887 GHz and Q value of 147, which is implemented with four W-shaped meander line resonators, is designed by Finite Element Method. Its corresponding electromagnetic resonance mechanism is explored to reveal absorption characteristics, build its corresponding equivalent circuit model, and guide the design of the palindromic microfluidic channel. The sensor shows a high sensitivity of 500 MHz/ε r , and the corresponding sensing performance is experimentally validated by the fact that the distinguishable resonance absorption frequency shift is 461 MHz, 458 MHz, 449 MHz, 444 MHz, and 436 MHz when rapeseed oil, corn oil, peanut oil, sesame oil, and olive oil are loaded into the microfluidic channel, respectively. The identification is successfully achieved according to the resonance absorption frequency shift. Moreover, a good agreement between the simulated and measured results demonstrates that the proposed meta-surface-inspired sensor is a promising candidate to monitor and determine the quality of edible oil to some extent, and is relatively valuable to the modern agriculture and food industry.
