Implantable Outlet Powers Medical Devices Under Skin
26 Jul
Summary
- A novel implantable outlet allows powering devices beneath the skin.
- Needle access provides a temporary connection for charging and data.
- The device remained safe and functional in animal tests for over a year.
Researchers at the University of California, Irvine have engineered an innovative Implantable Bioelectronic Outlet (IBO) designed to keep medical devices sealed beneath the skin. This submerged interface provides a solution to the infection risks associated with exposed sockets and the bulkiness of wireless charging antennas.
The IBO utilizes a porous, sponge-like material coated with conductive polymer and insulated with silicone rubber. This design allows a fine needle to access the device for charging or data transfer without permanent exposure. Early tests have shown significant promise, with data transfer rates reaching 16 Mbps, matching the maximum speed of connected implants.
Rigorous testing, including over 100 needle insertions and implantation in mice for more than a year, confirmed the device's durability and safety. Researchers observed no degradation or complications, highlighting its potential for long-term medical use. Future applications may involve topical anesthetics or specialized coatings to further enhance patient comfort.
