Ultralow Power Transistors Function for Years Without Batteries

Ultralow Power Transistors Function for Years Without Batteries

Electronics News Updates / By

Researchers at Cambridge University have just achieved a spectacular breakthrough in electronics design. They have developed new ultralow power transistors that could function for months or even years without a battery. These transistors look for energy from the environment around, thus reducing the amount of power used. Dr Sungsik Lee, one of the researchers at
