無線充電，連接，小型和低功耗關鍵個人健康技術

　　行業分析師預測，個人健康監測設備的數量將由現在的2016左右，由明年的約500萬上升到明年的約1000萬。這些設備，必要時，是小的，不顯眼的，易于維護-通常由病人自己。由于健康監測的性質，它很可能的設備也將需要密封，或者，至少，很容易清洗使用醫療級洗滌劑。這需要無線連接和無線充電。由于他們可能會被要求在不中斷的情況下持續運作，低功耗解決方案的需求也變得明顯。

　　另一個必要的功能，將對安全的需要；健康保險流通與責任法案（HIPAA）制定的美國1996只是一個例子，如何將征收的立法來保證數據的安全性。它將落在原始設備制造商實施必要的安全水平，以維持符合這種立法。今天許多MCU嵌入式安全功能特征，而所有的通信協議目前部署在大量的安全元件內置在他們的核心。滿足家庭健康設備的預期需求的關鍵將是與現有的技術能力相匹配的市場需求，并在必要時，開發新的解決方案。

　　Ad-hoc Infrastructure

　　Currently， the infrastructure for home medical devices is rudimentary， involving standalone devices （such as blood glucose testers）， devices that can gather data for access via USB/PC， or simple monitors that can connect via Bluetooth to a Smart Phone. While all of these devices have established a place in the market， the real benefits of ‘telehealth’ will come from connected devices seamlessly monitoring more complex parameters （such as blood pressure， respiratory rate or movement） and securely transferring that information to healthcare professionals， for patients with long- or short-term health conditions that require constant monitoring.

　　In this scenario， the need for a more sophisticated infrastructure is clear： one that will be secure enough to protect confidential data but flexible enough to allow devices to join/leave the network easily. At the heart of a home health infrastructure would be a ‘hub’ or Gateway. Typically this would be based on a highly integrated solution designed for the purpose， such as the i.MX28 family from Freescale. It forms the basis of a Home Health Hub reference design （Figure 1）， which Freescale has bundled with the iDigi Telehealth Application Kit.
