A pacemaker runs on a battery that eventually needs to be replaced, a task performed surgically. In addition to surgery costs up to $45,000, there is the ever-present risk of infection. In response, it is possible to convert the mechanical energy of heart into electrical energy and use it as a power source for the pacemaker, eliminating the battery. In this session, attendees will learn: pacemakers operate on low frequencies hence design should be such that it operates in low frequencies and also with less loss. In order to satisfy above considerations LTC3588-1 chip is used, the Minisense100 piezoelectric vibration sensor mounted parallel onto LTC3588-1 chip & the LTC3588-1 integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter, and an ultralow quiescent current under voltage lockout mode allows charge to accumulate on input capacitor until buck converter can efficiently transfer a portion of the stored charge to the output.
