Cost-effective portable alternative to the traditional defibrillator

Cardiac arrest is the number one cause of global deaths, 80% of which happen at home

Defi is an easy to carry device operated by using a mobile phone as a power source and computing unit for its operation. The technology exploits the fast-charging standards of modern mobile phones to increase the phone's voltage from 3.7V to 2000V for supplying the defibrillation shock.
