A wireless subcutaneous charger will be able to power medical devices. Description of biodegradable power supply published in the journal Science Developments.
Most bioelectronic devices, including sensors or drug delivery systems, are generally limited by battery capacity. They can be connected to an external power source, but this is inconvenient and carries the risk of infection. In a new study, scientists tested a prototype power supply on mice. It can be charged wirelessly through the skin or receive energy from processes inside the body.
In mice, the wireless implant lasted up to 10 days and completely dissolved within two months, proving its biodegradability. But development could potentially take longer; This requires the use of a thicker protective coating consisting of wax and polymer. The prototype device used two inductors: one was placed under the skin of the mice, and the other was placed outside, powering the first. Energy was stored in the zinc battery.
The researchers also tested the wireless charger as a drug delivery system. He gave anti-inflammatory drugs to mice with fever. After 12 hours, the body temperature of mice without the implant was much higher than that of mice with the chip. This shows that the device is successful in releasing the drug.
