PARIS, April 2, 2025 (BSS/AFP) - Scientists said Wednesday they have developed the world's tiniest pacemaker, a temporary heartbeat regulator smaller than a grain of rice that can be injected and ...

Terms of Service and Privacy Policy. A dissolvable pacemaker that’s smaller than a grain of rice and powered by light could become an invaluable tool for saving the ...

Tiny pacemaker is paired with a small, soft, flexible wearable patch that sits on the patient's chest. The wearable patch detects irregular heartbeats and automatically emits pulses of light.

Though a Northwestern-developed quarter-size dissolvable pacemaker worked well in pre-clinical animal studies, cardiac surgeons asked if it was possible to make the device smaller. To reduce the size ...

The pacemaker is powered by what is called a galvanic cell, which uses the body's fluids to convert chemical energy into electrical pulses that stimulate the heart.

The tiny pacemaker sits next to a single grain of rice on a fingertip. The device is so small that it can be non-invasively injected into the body via a syringe. Northwestern University engineers ...
