Pretty neat how technology is advancing healthcare:

Sometime next year nurses may put active band-aids on hospital patients to wirelessly monitor as many as three vital signs. Startup Toumaz Technology (Abingdon, U.K.) described its custom chip to power such a disposable device at the International Solid State Circuits Conference here Monday (Feb. 4).
The chip is one of an emerging group of smart wearable devices that ultimately aim to help patients get medical monitoring from the comfort of home.
“We not only have an aging society, but one that does not have healthy lifestyle,” said Alison Burdett, director of technology for Toumaz. “There are increasing numbers of people with chronic ailments, and that’s putting an enormous burden on health care systems worldwide,” she added.

Despite the custom design, the active patch is expected to cost as little as $5 when it hits the market next year.

The chip can interface to sensors for an electrocardiogram, a three-axis accelerometer, as well as blood glucose, ph-level and pressure monitors. It can only measure from one sensor at a time but does have a capability to switch between three sensors.
