No Battery, No Problem – Enabling Dependable Communication and Intelligent Computation on Batteryless Intermittent Systems

The demand for pervasive sensing and intelligent systems continues to grow, touching many aspects of human life – e.g., industrial, agricultural, environmental, health, and space. To achieve the full potential of such pervasive deployment, many of the resulting trillions of devices will be in hard to access locations, require low maintenance, and demand low cost. Wired and battery-based systems are a poor fit for such needs. To address this, the batteryless system paradigm has emerged where devices are solely powered by ambient energy harvesting. Unfortunately, harvested power is often extremely low and variable, directly impacting the dependability of intelligent computation and node-to-node communication using batteryless systems. This talk presents our insights and recent system prototypes that can be leveraged by hardware-software systems to tame these batteryless system challenges.
