A pacemaker is a device that helps control

an irregular heartbeat by sending electrical pulses to the heart’s chambers.

The first implantation of a fully implantable pacemaker occurred

all the way back in 1958. Since then,

there have been numerous advances in the field,

with devices growing smaller and more efficient over time.

Recently, scientists created the smallest pacemaker

in the world. In fact, it is even smaller than a grain of rice!

This temporary heartbeat regulator

is injected into a patient and controlled via light signals before completely dissolving.

At the moment, this breakthrough technology is still years away from human trials.

However, it is being lauded as a transformative technology that could potentially

prompt significant medicinal advances in the future.

Currently, there are millions

of people across the world who live with permanent pacemakers.

However, the team was motivated to create
