  • Introduction: Implantable medical devices such as cardiac pacemakers have the potential to benefit greatly from self-powered technologies that can extend device operation time and reduce the need for high risk repeatable surgeries. One promising approach is the use of inertia-driven triboelectric nanogenerators (I-TENGs) that can harvest biomechanical energy from the body's natural motions
  • Methods: In articles, a compact coin battery-sized I-TENG is demonstrated that is capable of generating 4.9 μW/cm3 of root-mean-square power output from body movements. Through preclinical testing, the I-TENG was shown to successfully charge a lithium-ion battery and was integrated directly with a cardiac pacemaker, enabling the pacemaker to operate in a self-rechargeable mode
  • Results: This proof-of-concept device represents an important step towards the development of truly self-powered implantable medical technologies that can operate indefinitely without the need for battery replacement surgeries.
  • Conclusion: The successful integration of the I-TENG with a functioning cardiac pacemaker highlights the potential of this approach to transform the field of implantable devices and improve patient outcomes.
