The document discusses putting individuals' bodies and health data online through wireless body sensors called "LifeChips". It describes how advances in sensors, nanotechnology, and cell phones enable real-time sensing of bodily functions through a body area network. Stored in the cloud, this data allows for cross-population comparisons and drives behavior change towards wellness through biofeedback. The University of California, Irvine is collaborating on projects merging microelectronics and life sciences through their LifeChips program and eHealth collaboratory.
