00:00This is the world's smallest pacemaker, next to a grain of rice, and now next to a normal pacemaker.

00:06That big thing is typically inserted into your body during surgery to regulate your heart rhythm

00:10by using electrical signals that stimulate your heart muscles to contract.

00:13And it might have wires that need to come out of your body.

00:15But this pacemaker is so tiny it can fit on the tip of a syringe.

00:19The goal is a non-invasive way to help babies born with heart defects.

00:23It works like a battery, using electrolytes in the body's fluid to convert chemical energy into electrical pulses.

00:28And it's controlled by this tiny wearable light that sends infrared pulses through the skin at the rate that the heart should beat.
