Summary

Researchers developed a battery-free, self-powered intracardiac pacemaker using cardiac motion. This innovative device, implanted via catheter, converts heart movement into electricity to treat arrhythmia in animal models.

Area of Science:

Bioelectronic devices
Biomedical engineering
Energy harvesting

Background:

Implantable bioelectronic devices require reliable power sources.
Cardiac motion presents a potential source of biomechanical energy.
Current pacemakers face limitations related to battery life and replacement.

Purpose of the Study:

To develop a battery-free, self-powered intracardiac pacemaker.
To utilize triboelectrification and electrostatic induction for energy conversion.
To evaluate the device's efficacy in treating arrhythmia in large animal models.

Main Methods:

A capsule-shaped device was designed for transcatheter implantation in the right ventricle.
The device leverages the coupled effect of triboelectrification and electrostatic induction.

Implantation was performed in swine via the intravenous route, followed by a three-week observation period.

Main Results:

The self-powered intracardiac pacemaker was successfully implanted and maintained endocardial pacing function.
The device effectively converted cardiac motion energy into electrical energy.
In vivo measurements yielded an open circuit voltage of approximately 6.0 V and a short circuit current of 0.2 μA.

Conclusions:

This study demonstrates a novel approach for battery-free cardiac pacing.
The developed device offers a promising solution for powering implantable bioelectronic devices.
This technology may overcome energy limitations in pacemakers and other medical devices for therapy and sensing.
