Plenty of nefarious applications for this. The range alone blows away existing RFID designs, which will make it the preferred "chipping" technology for surveillance states everywhere.

There are positive uses. I can see this being useful for monitoring health in animals raised for food in addition to the medical applications the article mentioned.

That said, the potential for abuse is limited by what society will tolerate. We tolerate tracking and alcohol monitoring bracelets for people who drive drunk. If we tolerate tracking implants for sex offenders on parole or something I'm sure it'll filter down routine probation sentences eventually.

How much energy could a device extract from blood sugar?

"One single implanted GBFC device of 0.24 mL volume (2.4 mL for the whole implant) produced the power required to operate, using a specially designed electronic circuit to charge a capacitor, two types of electronic devices: a LED and a digital thermometer."

I'm waiting for someone to invent the implantable chip that converts blood sugar into heat/light purely with the intention of wasting that energy.

Grab enough power to monitor blood sugar, to make sure you aren't putting someone into a coma, but otherwise just try to burn an extra few hundred calories a day.

That's interesting. Seems like a low tech solution would be to give blood every day. I wonder if somebody has already invented the blood donation diet.

It would be an enormously complex device, most of the sugar we consume gets converted into fat as we quickly cap out our "energy blocks".

Why waste this energy? Couldn’t they devise a way to mine bitcoin with it? :)
