近年來，人類在各項科技領域的發展大幅進步，例如：無線通訊技術、嵌入式系統以及感測技術等，將這些技術結合起來而發展出的系統稱為網宇實體系統，網宇實體系統可說是多個實體裝置的互動網路，科技發展讓網宇實體系統能夠應用在更多方面，我們將網宇實體系統應用在醫療資訊領域，以往的醫療設備是針對單一個體所設計，透過無線通訊、嵌入式技術和硬體開發的提升，我們可以將這些技術應用在監控病患的健康狀況，因此，我們在此篇論文提出一套基於Android平台與網宇實體系統的智能醫療援助系統。
我們的系統將生理資訊感測器整合在Android作業系統上，開發出可供配戴的生理監控模組，利用此模組可以長時間的量測使用者的心跳與體溫，並即時將此生理資訊顯示於生理監控模組上回饋給使用者，此外，這些生理資訊也會透過網際網路傳送到我們系統中位於雲端的其他裝置，我們系統裝置之一的雲端管理平台能夠將使用者的生理資訊儲存，並提供界面給醫護人員，方便監測使用者，若使用者發生緊急狀況，我們可透過系統裝置之一的終端監控平台發出語音指令，該指令將於生理監控模組端以語音方式播出，達到緊急救護的功能，雲端管理平台同時也會將使用者的GPS位置及路徑規劃提供給外部的緊急救援系統，以減少不必要的時間浪費，達成及時救援的功能。

Recently, each field of technologies has been substantially improved, such as wireless network and communication, embedded systems and sensor network. The system combining with all the mentioned technologies above is a so-called cyber-physical system. Cyber-physical systems are kind of interactive network of physical devices. Cyber-physical systems can be applied in more aspect by the improvement of technologies and we apply cyber-physical system in medical information field. We apply the technologies, such as wireless communication network and, embedded systems and the improvement of hardware development, in monitoring the patients’ health. In this paper, we have proposed a Smart First Aid System in Android with Cyber Physical System.
We integrated bio-sensors on Android platform, developing a wearable bio-information monitoring device. We can collect user’s vital signals by this wearable bio-information monitoring device and immediately show the bio-information on the display module of wearable bio-information monitoring device. Furthermore, these vital signals would be sent to the other devices in our system by internet. The server in our system would store those vital signals in database and provide graphical user interface for healthcare center to monitoring the health of user. In case of emergency, we could send voice instructions by our healthcare application to the wearable bio-information monitoring device, and the voice instructions would be broadcasting by the voice module of the wearable bio-information monitoring device for the first-aid. In the same time, our server would send the user’s GPS location and the planning path to the external emergency center, in order not to waste times for the emergency aid.
