The object
Esther Sans Takeuchi invented the Li/SVO battery that powers implantable cardioverter defibrillators. Her long-lived lithium/silver-vanadium-oxide cell gave implantable defibrillators the high-energy, reliable power source needed to monitor and treat dangerous heart rhythms for years. That reliability is vital when a patient depends on an implanted device.
01
What Esther did
Invented the Li/SVO battery that powers implantable cardioverter defibrillators.
02
Why it matters
The battery chemistry is a consequential implantable-device component used in cardiac defibrillators.
