Researchers at Northwestern University just found a way to make a temporary pacemaker that’s controlled by light—and it’s smaller than a grain of rice. A study on the new device, published last week ...

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 have ...

Scientists just unveiled the world’s tiniest pacemaker. Smaller than a grain of rice and controlled by light shone through the skin, the pacemaker generates power and squeezes the heart’s muscles ...
