Case Study: Resonant Link and Resonetics Team Up to Deliver 20-Minute Wireless Recharging

What if we could eliminate the drawbacks of implantable medical devices like spinal cord stimulators and implantable cardioverter defibrillators? What if patients didn't hesitate to want, and clinicians didn't hesitate to recommend these life-changing devices? What would need to change?

One of the biggest drawbacks of many implantable medical devices available today is their power and energy requirements. Limitations like hours-long, frustrating recharging or battery replacement surgeries when non-rechargeable batteries run out lower the number of people who want the devices and patient quality of life for those who do get them.

For implanted medical devices that are encased in titanium, these limitations are even more pronounced. This is because:

  1. Many titanium-encased devices are designed for monitoring and treatment of chronic conditions that by nature, require more power because they're always in use.
  2. It's really hard to design patient-friendly power and energy for implantable medical devices encased in titanium.

Put simply, these devices need more power and it's harder to give them more a power in the way that patients want.

Resonant Link and Resonetics teamed up to solve this challenge. The result is 20-minute recharging of titanium-encased implantable medical devices. Patients can recharge during an episode of their favorite show or move around while recharging. In the time it takes to make breakfast for the kids or walk the dog, their spinal cord stimulator or pacemaker could recharge.
