本論文主要係研製一型應用於複數介電常數量測之非接觸式介質量測系統及一型應用於人體吸呼及心跳量測之非接觸式雷達教學模組。非接觸式介質量測系統係以無線傳能原理，於固定耦合距離條件下，設計平面式線圈共振器，藉由線圈磁耦合共振達到非接觸式能量傳遞。將線圈連接至雙埠向量網路分析儀，且分別量測空置及放置待測物之系統雙埠散數參數，擷取變化量，用以計算待測物之複數介電常數。量測實驗則可分為單一待測物及雙介質量測。單一待測物量測分別以平面基板及立體介質圓柱進行實驗，雙介質量測同時使用兩組不同材質之平面基板進行實驗。生理參數感測雷達教學模組則是基於都卜勒原理，以市售積體電路、微帶線天線及射頻被動電路實現之大學部「射頻模組實習」課程教材。此雷達感測模組之操作頻率為2.5 GHz，模組與人體量測距離約為50 cm，其心跳量測結果與市售醫療級血氧濃度計之量測結果比較，誤差可控制在每分鐘1次內，誤差百分比為1.33 %。

This thesis presents a non-contact permittivity measurement system and a non-contact vital-sign sensor radar for human’s respiration and heartbeat detection. The developed permittivity measurement system based on the principle of wireless power transfer is mainly composed of two strongly coupled planar loop resonators, which transfer power by the mutual magnetic coupling at a fixed separated distance. In the measurement setup, two loop resonators are respectively connected to port 1 and port 2 of the vector network analyzer to acquire two- port scattering parameters with and without the subject under test (SUT), and then the complex dielectric constant can be determined by calculating the difference of two sets of measured parameters. To demonstrate the proposed system, two types of planar substrate and a dielectric cylinder are chosen as the SUTs to perform the tests with single SUT or simultaneous two SUTs.
The developed sensing radar module based on the Doppler principle includes radio- frequency (RF) ICs, passive components, microstrip antennas and baseband circuits. The aim of the radar module is to develop teaching materials for “radio frequency module laboratory”. The radar module is designed at 2.5 GHz. Under a measurement distance of 50 cm, the measured error of the heartbeat rate of the developed radar module is controlled under 1 time per minute, namely a relative error of 1.33 % as compared with the result measured by a medical finger pulse oximeter.
