Heart Is Where the Chips Are, Helping Keep the Beat

Researchers at Rice University have demonstrated a wireless pacemaker array that opens new possibilities for medical sensors.
The team worked with cardiologists at the Texas Heart Institute to design a pacemaker that would insert a network of chips the size of a grain of rice in different locations inside the heart; the chips would communicate with a base station under the patient's skin, charging via radio frequency energy harvesting. When the base station detects a heart rhythm problem, it signals the embedded chips to release a jolt of energy to restore the normal rhythm.
The new device addresses shortcomings with current pacemakers, which the researchers say are effective only in pacing a single chamber of the heart.
