Doctors Praise “No More Surgery” As New Ultrasound Tech Recharges Pacemakers Pain-Free And Fast

The medical technology landscape is witnessing a groundbreaking shift, courtesy of a South Korean research team. Their innovative approach to recharging implantable medical devices without surgery is set to revolutionize patient care. As the prevalence of conditions necessitating these devices increases, so do concerns about their long-term sustainability and safety. The traditional method of replacing exhausted batteries through surgery poses significant risks and discomfort to patients. This new ultrasound-based wireless charging solution promises to alleviate these concerns, offering a safer and more efficient alternative that could redefine patient care standards.

Revolutionizing Medical Device Charging

The innovative system developed by Professor Jinho Chang and his team at the Daegu Gyeongbuk Institute of Science and Technology (DGIST) leverages dual piezoelectric layers to convert ultrasound waves into electricity. This novel approach allows the system to safely recharge implantable device batteries without the need for surgical intervention. The first layer captures incoming ultrasound waves, while the second layer harnesses residual energy, effectively doubling the power output compared to conventional methods.

By optimizing the design through simulations, the researchers achieved a power density of 497.47 milliwatts per square centimeter in water. This translates to fully charging a 140mAh battery in just 1.7 hours. Such efficiency marks a significant advancement in the field, addressing a long-standing challenge in the management of implantable medical devices. The potential to decrease the frequency of surgical interventions cannot be overstated, offering a beacon of hope for patients worldwide.

Testing the Technology’s Limits

To ensure the technology’s real-world applicability, the research team conducted tests using pig tissue to simulate human anatomical conditions. Even with a 30mm-thick tissue layer, the harvester managed to deliver 312.34 milliwatts of power, demonstrating its robust performance. These experiments underline the technology’s ability to function efficiently under realistic conditions, a critical factor for its eventual adoption in medical settings.

Professor Chang highlighted the technology’s potential, stating, “This research presents an innovative technology that effectively harvests ultrasound energy, which has not been fully utilized in the past, for wireless charging of implantable medical devices.” Such advancements pave the way for reduced surgical interventions and could lead to the development of smaller, more efficient electronic implants.
