Posting about implants reminded me to check in on how medical technology is moving the personal interface to technology over and under the skin in interesting ways.

“The monitor measures glucose from interstitial fluid located just underneath the skin by sending a tiny electric current through the skin. The Glucose Watch has a 3-hour warm-up period and could provide painless, noninvasive measurements of blood sugar every 20 minutes for up to 12 hours. The Glucose Watch is not intended to replace traditional finger stick glucose monitoring, instead it should be used to supplement monitoring.”
