Scientists Implant Biofuel Cells Into Rats

RedmondChris writes "A team of scientists from Joseph Fourier University in France have successfully implanted biofuel cells into rats, generating 6.5 microwatts by harnessing the power of glucose. From the article: 'The device uses enzymes to harvest energy from glucose and oxygen found naturally in the body. Past attempts at using such a device in animals have failed because the enzymes have required acidic conditions or were inhibited by charged particles in the fluid surrounding cells. But Philippe Cinquin and his team from Joseph Fourier University in Grenoble, France, overcame these obstacles by confining selected enzymes inside graphite discs that were placed into dialysis bags. Glucose and oxygen flowed into the device, but enzymes stayed in place and catalyzed the oxidation of glucose to generate electrical energy.'"

Enough power for a pacemaker?

[hrvatska]

After reading TFA, I was left wondering if this technique could be used to generate enough power to eliminate or reduce the need to replace pacemaker batteries.

Diabetics

Anyone consider the possibility of a device that not only produces energy from the body, but also uses up glucose? A device that conceivably could both help eat up Glucose and POWER a MONITOR to help see how the diabetic is doing??

I happen to be a highly insulin-resistant Type 2, and this was the first thing I thought of when I read this.

Re:effects on the host?

The major advantage is that it becomes a plausible source of power for implanted devices. Health monitoring devices but also storage, computer interfaces, pretty much anything you can imagine. This sort of technology makes cyborg implants much more plausible.
