Comparison of the two types of sensors.

No.	Resonance Frequency	Average Sensitivity ${}^{*1}$	$\mathsf{\Delta }\mathit{F}{}^{*2}$	Sensitivity ${}^{*3}$
Type 1 Sensor	5.25 GHz	8.75 MHz/$ϵ$	202 MHz	0.0024
Type 2 Sensor	5.25 GHz	10.28 MHz/$ϵ$	450 MHz	0.0031

${}^{*1}$ represents the average sensitivity obtained through relation of $\frac{\Delta F}{\Delta ϵ}$. ${}^{*2}$ represents the maximum frequency shift among all the chemicals. ${}^{*3}$ is the sensitivity obtained through (5).
