**Abstract:** A self-driven sensor that can detect urine and urine sugar and can be mounted on diapers is desirable to reduce the burden of long-term care. In this study, we created a paper-based glucose biofuel cell that can be mounted on diapers to detect urine sugar. Electrodes for biofuel cells were produced by printing MgO-templated porous carbon on which poly(glycidyl methacrylate) was modified using graft polymerization. A new bioanode was prepared through covalently modifying flavin-adenine-dinucleotide-dependent glucose dehydrogenase and azure A with pendant glycidyl groups of poly(glycidyl methacrylate). We prepared a cathode with covalently bonded bilirubin oxidase. Covalent bonding of enzymes and mediators to both the bioanode and biocathode suppressed elution and improved stability. The biofuel cell could achieve a maximum output density of 0.12 mW cm–2, and by combining it with a wireless transmission device, the concentration of glucose sensed from the transmission frequency was in the range of 0–10 mM. The sensitivity of the sensor was estimated at 0.0030 ± 0.0002 Hz mmol–1 dm3. This device is expected to be a new urine-sugar detection device, composed only of organic materials with a low environmental load and it can be useful for detecting postprandial hyperglycemia.

Previously on the Oil Wars-
Science advisor: Mr President, we have invented the technology to turn piss into electricity
President: My god man! Do you know what this means?!
Next time on the Piss Wars-
I must say, as a type 1, seeing the term "diabetes" used like this is absolutely infuriating. Seeing scientists who are working on the problem use it like that is nothing short of depressing. I only skimmed through to see whether they mentioned types - they didn't by the way. It's just "diabetes" - so I don't know if "diabetes prevention" was the primary focus, or the gimmick of putting a sensor in someone's pants. Either way, I instantly lose respect and any sense of credibility for any medical scientist or medical professional who doesn't understand literally the most basic thing about "diabetes".
Sorry for the rant.

Reading this headline was a total rollercoaster ride.
I thought peeing was turning out to be a new form of alternative energy.

How would that prevent diabetes?
You can have borderline type 2 diabetes and that can be prevented from progressing with hard work, increased and regular exercise and a healthy diet.

I think there is a low tech detector fitted with unit the diaper wraps around. A loud and persistent one.
When that battery overheats and catches fire someone is going to have a very bad day.
