(The Gist of Science Reporter) Pacemaker — Life-saving Discovery

(GIST OF SCIENCE REPORTER) Microwave — Hassle-free Heating

An engineer from Buffalo, New York, Wilson Greatbatch, accidentally invented the first implantable cardiac pacemaker which revolutionized the medical field and has saved millions of lives.
He was working on the heart sound monitoring instrument and had mistakenly positioned a transistor that was multiple times more powerful than the ones he generally used in the instrument.
He found the electrical heartbeats very similar to the human heartbeat.
He visualised that this new invention could be utilised as a pacemaker and spent some more time to making it implantable inside a patient’s body.
