The future of implantable devices is evolving, and there is an increased desire for wireless technology to power them.
“Our device may unlock next-generation biomedical applications because it can generate 300 percent higher power than the current state-of-the-art devices,” said Bed Poudel, research professor at Penn State and co-author of the study. The magnetic field and ultrasound energy often work at lower frequencies and might be used to charge implants wirelessly.The devices employ a sophisticated two-step process to convert magnetic field energy into electricity. The first layer, magnetostrictive, plays a crucial role by transforming a magnetic field into stress.
