What this research studies

This research focuses on creating a new type of power source for leadless cardiac pacemakers that is significantly smaller and longer-lasting than current lithium-based batteries. The innovative betavoltaic power source aims to reduce the battery size to just 0.1 cc while providing a consistent power output for up to 20 years. This advancement could allow for the implantation of leadless pacemakers in younger patients and enable more flexible device designs and implantation techniques. The project includes designing a biocompatible package to ensure safety and reliability.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients who require cardiac pacing and are suitable for leadless pacemaker implantation.

Not a fit: Patients who have contraindications for pacemaker implantation or those who do not require cardiac pacing will not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more effective and longer-lasting leadless pacemakers, improving the quality of life for patients with heart rhythm disorders.

How similar studies have performed: While the concept of betavoltaic power sources is innovative, similar approaches in miniaturizing power sources for medical devices have shown promise, indicating potential for success.
