Medical breakthrough – Pacemaker the size of a pencil tip!

Cardiac devices such as pacemakers are surgically implanted to monitor your heart’s functions. Being invasive, their implant comes with risks such as infections. Worst still, when their battery runs out, you have to surgically replace them. A team at the National University of Singapore has developed a new sensor, smaller than the tip of a pencil, that can be implanted under the skin using a syringe. Best of all, it does not need a battery – hence, no need to repeat any surgical insertion. Check out the details in this article!
