Vermont Patent of the Month – June 2025

U.S. Patent Application No. 20250183716, titled ‘High efficiency wireless power transfer to implantable devices’, introduces a breakthrough from Resonant Link Inc. aimed at reshaping how medical implants are powered. The invention enables wireless charging of devices like pacemakers and neurostimulators with much higher efficiency and safety than current methods.

Reimagining Wireless Power for the Body

Implantable devices often rely on outdated charging methods that require external leads or inefficient energy transfer. This new system uses tightly-coupled magnetic resonance to deliver power directly through tissue, reducing the need for frequent surgical replacements and minimizing heat buildup-two major challenges in the field.

Core Innovation

The design integrates adaptive control and alignment systems to optimize energy transfer even when the patient moves. It operates with minimal energy loss, increasing overall efficiency and reducing battery size requirements in implants. This could make devices smaller, longer lasting, and more comfortable for users.

Transformative Potential

This technology is particularly valuable for patients with chronic health conditions who depend on implanted devices for daily survival. By simplifying recharging and improving reliability, Resonant Link Inc. could significantly enhance quality of life and reduce long-term healthcare costs.

Next Steps

The invention has clear applications in cardiac care, neurostimulation, and insulin delivery systems. As it moves toward commercialization, it may become a key component of the next generation of bioelectronic medicine.
