A Tiny Wireless Pacemaker
Researchers at Rice University debuted a wireless, battery-less pacemaker that can be implanted directly into a patient’s heart. It was introduced at the IEEE’s (Institute of Electrical and Electronics Engineers) International Microwave Symposium (IMS) in Honolulu, recently.
The pacemaker harvests energy wirelessly from radio frequency radiation transmitted by an external battery pack. Pacemakers have not been traditionally implanted directly into a patient’s heart; they are placed away from the heart, where surgeons can periodically replace their on-board batteries with minor surgery.
