Materials & Methods Fig.1, show the QUASAR ECG sensor and Eco with a dime coin for reference of scale. ＊1. - 為了達到設計目標，已在上一段所描述，正在開發一種新的心電監護系統。 2.- QUASAR 是一種可穿戴式傳感器，微型，低功耗心電圖檢測設備，Eco 是一種超小型，低功耗的無線傳感器節點。
Materials & Methods ECG monitoring system divided into four subsystems: ECG Sensors, Data Sampling, Wireless Transmission, and Host Interface. ＊15.1 – 本篇的心電監護系統 分為四個部分 ： 心電傳感器 、數據收集、無線傳輸、主機接口。此圖又可分為三種型式 ：
Materials & Methods Uses the Eco for both data-sampling and wireless transmission. We can achieve data sampling as well as high communication throughput and low latency. But this architecture imposes extra cost and volume for the data-sampling. ＊16.1 –。此圖是使用兩個 MCU 結構 。一個負責資料收集，另一個負責處理 無線傳輸 。特點是 可以精確的收集 何 增加工作量 。但缺點是 增加額外的成本和體積。
Materials & Methods Uses the Eco for both data-sampling and wireless transmission. The number of ECG sensors that can be monitored simultaneously is limited. However, this is a very simple and low cost design. ＊17.1 – 生態數據採樣和無線傳輸 。 所有的 採樣訊號 直接儲存在 ADC 通道上。優點 是能使成本降低。缺點是能同時被監看的數量是有限的。所以只能使用在指有 2 . 3 個 ECG 的地方使用 。
Materials & Methods Uses one Eco node for each ECG sensor. This is also a more reliable and distributed architecture than the other two. The cost will increase in proportion to the number of monitoring points. ＊18.1 – 就只使用一個生態節點為每個心電圖傳感器。因此，我們可以實現更高工作量。這也是比其他兩個更可靠。 缺點是 需要更精密的 MAC層 設定，而且成本與監測點都將會增加。
Materials & Methods Is a compact ECG sensor that does not require skin preparation, gels, or adhesives. It measures only 15 mm × 3.8 mm and weighs 5 g. ＊19.1 – 如圖所示是一個緊緻的心電圖傳感器，不需要黏膠與黏合劑。尺寸為 15mm * 3.5mm 且重量僅為 5 g。可直接 嵌入在衣服裡。
