Yes. The Eterni™ Miniaturized Power platform delivers up to 500 mW of continuous wireless power or recharging for millimeter-scale implants, including delivering 10s of mW of power into a 3 mm implant. With Eterni™, Resonant Link Medical is one of the only wireless power providers capable of supporting the miniaturization trends driving next-generation bioelectronic medicine. The Eterni™ platform is pre-compliant and can be adapted and integrated into your device in months, so it’s perfect for device teams working on sub-centimeter implants looking to preserve capital, reduce risk, and get to market faster.
Eterni™ was built for teams pushing the boundaries of what's possible at a small scale. It's great for applications like neural recording, biomarker sensing, vagus nerve stimulators, peripheral nerve stimulators, deep brain stimulators, cochlear implants, and optic devices. Eterni™ supports both rechargeable and battery-free implants, and delivers up to 500 mW of wireless power through thick skull and tissue over a large misalignment window, so you're not trading performance for a smaller footprint.
If your team is pursuing miniaturization as a path to new therapy categories, smarter focal implants, or reaching patients who weren't candidates before, Eterni™ gives you a derisked foundation to build from that accelerates development, reduces risk, and frees resources to focus on what makes your therapy different.
Every device and therapy is different, and we can advise on how Eterni™ integrates into your specific wearable vision based on what we've seen work across dozens of implantable devices. Eterni™ is small enough to be worn discreetly and comfortably throughout the day, making it well-suited for applications that require continuous power as part of a patient's everyday life. It's equally capable for devices that don't need to be on all the time, supporting intermittent recharging use cases just as well. However your therapy needs to deliver power, we'll help you find an approach that works for your patients and fits naturally into how they live.
