David Peskowitz over at The Feature wrote yesterday about how Always-On medical applications might be implanted in your skin.

He, however, was talking about a specific product. UbiMon, from UbiCare, a project of the Imperial College in London, is precisely the system I've described before, measuring heart function so that a "critical event" can be detected before it happens and kept from becoming a fatal event. (Image is from UbiCare.)

I can't argue against what they're doing so I'll just offer a few observations.

• They're doing a lot more local processing than I envisioned.
  
• They're doing a lot more processing in general than I thought possible.
  
• They seem to be aiming at the high-end of this market, people at definite, specific risk for a specific nasty event. I think the market is broader.
  
• This is a research project, not a market test, so any criticisms I've made concerning the market are therefore inoperative.
  

One more word. Cool.
