pengju li and his colleagues at the university of chicago have created a wireless, ultrathin pacemaker that utilizes light similarly to a solar panel. because it conforms to the shape of the heart, its design reduces interference with the <\/span>heart\u2019s<\/span> normal function while simultaneously eliminating the need for batteries. their findings, just released in <\/span>nature<\/span><\/a>, provide a novel strategy for heart pacing and other therapies requiring electrical stimulation.<\/span><\/p>\n

medical devices called <\/span>pacemakers<\/span><\/a> are inserted into the body to control cardiac rhythms. they <\/span>are comprised<\/span> of<\/span> battery-operated electrical circuits with leads that are fixed to the heart muscle to stimulate it. leads, however, can break and cause tissue damage. once implanted, <\/span>the <\/span>leads\u2019<\/span> position cannot be altered<\/span>, <\/span>which restricts<\/span> access to various cardiac areas. because they use stiff iron electrodes, pacemakers could also cause tissue injury when they are used to regulate <\/span>arrhythmia<\/span><\/a> or to restart the heart after surgery.<\/span>
