　　无线充电，连接，小型和低功耗关键个人健康技术

　　行业分析师预测，个人健康监测设备的数量将由现在的2016左右，由明年的约500万上升到明年的约1000万。这些设备，必要时，是小的，不显眼的，易于维护-通常由病人自己。由于健康监测的性质，它很可能的设备也将需要密封，或者，至少，很容易清洗使用医疗级洗涤剂。这需要无线连接和无线充电。由于他们可能会被要求在不中断的情况下持续运作，低功耗解决方案的需求也变得明显。

　　另一个必要的功能，将对安全的需要；健康保险流通与责任法案（HIPAA）制定的美国1996只是一个例子，如何将征收的立法来保证数据的安全性。它将落在原始设备制造商实施必要的安全水平，以维持符合这种立法。今天许多MCU嵌入式安全功能特征，而所有的通信协议目前部署在大量的安全元件内置在他们的核心。满足家庭健康设备的预期需求的关键将是与现有的技术能力相匹配的市场需求，并在必要时，开发新的解决方案。

　　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.
