Intermittent Computing

Content of the lecture:

Traditional energy-harvesting systems buffer energy in storage devices, such as supercapacitors or batteries, so that systems can keep working for period where harvested energy is insufficient. Intermittent computing takes another approach: simply use energy when it is available, and power-down the system when it’s not. By using low-power non-volatile memory technologies, it is now possible to save the system state into memory when power is lost, and to restore it when power returns. In this lecture, we will look at the strategies and challenges of intermittent computing technologies, and the suitability of applications such as a self-powered cycle computer.
