隨著醫療進步及老化人口的增加，藉由行動載具的使用來增加其活動功能的需求也會持續快速增加。智慧型載具的發明，可幫助行動不便或是長期臥床之下肢癱瘓者由坐姿轉為站姿，以及移位的功能。然而智慧型載具的使用上，從坐姿轉為站姿的過程中，必需考慮病患本身的身體狀況。才能夠避免因姿勢改變而引起的病症，造成使用者更進一步的傷害。
有鑑於此，本研究希望建立一套生理參數監測系統，來監測智慧型載具使用者其生理狀況。其中監測的生理參數有心電圖、呼吸率以及血壓，同時利用藍芽無線傳輸技術，結合電腦系統所開發的監控平台做長時間的即時監測與分析。
系統主要架構可分為兩個部份；第一部份為生理訊號之擷取，利用微控制器（PIC24F）單晶片做訊號處理，並透過藍芽無線傳輸模組，將數值變化傳送到電腦端的監控平台上。第二部份為監控平台的訊號顯示、即時分析、以及儲存生理參數資料。並在生理訊號異常時，經由回傳警示訊號的方式，在最短時間內達到預警的功能。

With the progress of medical technology level and the increasement of aging population, the demand for move assistive devices follows to increase. The invention of smart carrier helps paraplegic patients to change body posture and position. In order to prevent the damage due to posture change, the patient’s physiology conditions need to be monitored when using smart carrier.
The aim of this study is to set up a physiological monitoring system. Physiological parameters such as ECG, respiratory rate and blood pressure are monitored. The data transmit to the monitoring system via Bluetooth wireless technology for long-term real time monitoring and analysis.
A wireless portable device based on microcontroller（PIC24F）is used to acquire the physiological signals and then transmit them to the monitoring system via Bluetooth wireless technology. The acquired signals and waveform are displayed on a screen and saved for further processing. Furthermore, when the physiological signal is unusual, a warn signal will be sent to provide early warning in the shortest time.
