Researchers at ETH Zurich and the University of Basel have developed an experimental subcutaneous electronic device, named Echo, designed to regulate blood sugar levels without drugs, enzymes, or living cells. The device uses an electrocatalytic process to convert excess glucose into gluconate, a benign compound that the body can naturally excrete through urine.

The implant utilizes a 3D-printed housing with a graphite felt sponge decorated with gold nanoclusters and platinum particles. When triggered by an electrical impulse, the catalyst oxidizes glucose directly. The system is designed as a closed-loop mechanism where a continuous glucose monitor communicates via Bluetooth to a smartphone, which then wirelessly activates the implant using radio frequencies.

In animal trials involving overweight mice with diabetes, the system successfully normalized blood sugar levels within one hour. Beyond glucose regulation, the technology also promoted the use of stored fat in test subjects, suggesting a potential dual approach to treating comorbid diabetes and obesity.

## Claims

- The implant uses an electrically powered catalyst to convert excess glucose into gluconate. (reported by 3 sources)
- Gluconate is a lower-energy metabolite that is excreted through the kidneys. (reported by 3 sources)
- In mouse models, the implant normalized blood sugar levels within one hour. (reported by 2 sources)
- The system uses gold nanoclusters coated with platinum particles on porous graphite felt as a catalyst. (reported by 2 sources)
- The device is wirelessly powered at a frequency of 13.56 megahertz. (reported by 2 sources)
- The implant promoted the use of stored fat in diabetic mouse models. (reported by 1 source)
