摘要：
In this paper, a simple, miniaturized, flexible device has been introduced for composition detection of a liquid. The proposed 7mm x 7mm x 0.17mm structure offers higher sensitivity compared to the previously reported sensors operating in microwave regime. The sensitivity is about 0.53% using only 18.24 mu L sample. The novelty lies in its flexibility in contrast to the other sensors for liquid characterization making it compatible to wearable, real time and on body sensing applications. In addition, the introduced numerical equations facilitate the dielectric properties' evaluation of an unknown liquid.
