9. NeuroPace
Around 50 million people of the world suffer from a neurological disorder known as epilepsy. Thanks to the inventor of NeuroPace for creating such a wonderful device that could predict oncoming seizures by implanting sensors in epileptics’ brains. Next, it starts working as a defibrillator and preventing the seizure by sending electrical pulses to stop the erratic signals of the brain. This amazing device got available in 2014 after 8 years of clinical trials.
