Overview

• The pacemaker, measuring 1.8mm by 3.5mm by 1mm, is the smallest ever developed and can be injected using a syringe.
• It is powered by a galvanic cell that uses biofluids to generate electricity and is activated by light pulses from a wearable chest patch.
• Designed for temporary use, the device dissolves harmlessly in the body, eliminating the need for surgical removal and reducing risks like infection and tissue damage.
• The primary application is for newborns with congenital heart defects, offering a safer, less invasive solution for critical post-surgery pacing needs.
• The technology has been successfully tested on animal models and human heart tissue, with human trials anticipated in 2-3 years, and potential uses in bioelectronic medicine like nerve regeneration and pain management.
