The new pacemaker works by using the kinetic energy of the heart

Modern pacemakers are battery-powered to keep the patient's heart beating regularly.

The problem is that they need replacingbatteries, which implies additional operations. And this is always risky. Yi Zhiran from Shanghai Jiao Tong University decided to create a fundamentally new device that is powered by the kinetic energy of the heart itself.

The practical strength of the heart is 0.5 newtons, that is, the output power is 192 microwatts, the authors of the development note. At the same time, a minimum of 10 microwatts is sufficient for the smooth operation of a commercial pacemaker.

The energy for the operation of the device is collected by bendinghermetically sealed pacemaker design, creating curved piezoelectric energy. This feeding method is very different from modern pacemaker designs.
