Doing that with present-day technology is a challenge, not least because collecting and transmitting all of the data that can be gathered by even a handful of motion and vital-signs sensors would be a huge drain on battery power and wireless bandwidth.By equipping the clothing and bodies of users with a mesh of multiple sensors - known as "smart dust" - that report to an Android-powered phone, researchers are pioneering an open-source route to realizing the dream of always-on medical monitoring. Their work has already allowed them to measure how much test subjects exercise, how well their hearts are doing and how much air pollution they're being exposed to.The resulting data have a number of applications:Incorporation of historical and real-time data on vital signs into permanent medical records Automatically inform a patient when to adjust their heart medication Turn exercise and daily activity levels into a Foursquare-style competition Allow users to avoid locations and times of day when air pollution is worst The technology (pdf) is described in a paper to be delivered in late June at the 2010 International conference on Pervasive technologies for assistive environment in Samos, Greece. It outlines a hierarchy of processing steps that make 24/7 monitoring of vital signs (such as breathing and heart rate) realistic given the battery life issues and bandwidth constraints of mobile phones Three-layer architecture of the DexterNet system with example hardware, communication and software implementation. This hierarchy, known as DexterNet, includes sequential processing at each level of the hardware involved: the sensors, known as the body sensor layer, the smartphone orpersonal network layer, and finally in the "cloud" or global network layer that backs up and does...
