無(wú)線(xiàn)充電，連接，小型和低功耗關(guān)鍵個(gè)人健康技術(shù)

　　行業(yè)分析師預(yù)測(cè)，個(gè)人健康監(jiān)測(cè)設(shè)備的數(shù)量將由現(xiàn)在的2016左右，由明年的約500萬(wàn)上升到明年的約1000萬(wàn)。這些設(shè)備，必要時(shí)，是小的，不顯眼的，易于維護(hù)-通常由病人自己。由于健康監(jiān)測(cè)的性質(zhì)，它很可能的設(shè)備也將需要密封，或者，至少，很容易清洗使用醫(yī)療級(jí)洗滌劑。這需要無(wú)線(xiàn)連接和無(wú)線(xiàn)充電。由于他們可能會(huì)被要求在不中斷的情況下持續(xù)運(yùn)作，低功耗解決方案的需求也變得明顯。

　　另一個(gè)必要的功能，將對(duì)安全的需要；健康保險(xiǎn)流通與責(zé)任法案（HIPAA）制定的美國(guó)1996只是一個(gè)例子，如何將征收的立法來(lái)保證數(shù)據(jù)的安全性。它將落在原始設(shè)備制造商實(shí)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(xié)議目前部署在大量的安全元件內(nèi)置在他們的核心。滿(mǎn)足家庭健康設(shè)備的預(yù)期需求的關(guān)鍵將是與現(xiàn)有的技術(shù)能力相匹配的市場(chǎng)需求，并在必要時(shí)，開(kāi)發(fā)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.
