COVID may be the proxy, but we should have this as a general purpose health platform. There are a variety of attributes to sense, but the difficult issues in implementation will be the larger system level integration: - How to power it reliably - The system needs to be 'transparent' to the wearer in many senses of the word. Put it on and forget it indefinitely whether sleeping, showering or exercising. - It needs to be rugged to withstand any type of vigorous human activity: Triathlons, skydiving, roller coasters, dance contests, ... - Likely, analysis systems will improve to enable early and accurate alerts. Where will those systems run? On our smart phones? in the cloud? - The entire system needs to be low-cost. In fact, health insurance companies may want to offer them at no charge to their clients. - Aaaaaand privacy... In some senses, the actual sensor suite is a secondary design concern behind the system platform and architecture
