As of now, batteries power these devices. Batteries, however, are large, expensive, and short-lived - even the rechargeable ones wear out in a few years. Therefore, they are not a sustainable powering solution. Tiny battery-less devices promise a maintenance-free and environment-friendly alternative. They operate by harvesting energy from the environment. Ambient power, however, is marginal and unpredictable. This causes tiny energy-harvesting devices to operate intermittently, violating the requirements of many real-world applications.This work presents an event-based command-recognition algorithm tailored towards battery-less sensors, taking into account the challenges of intermittent execution and the ultra-low-power hardware. Our algorithm achieves a 97% recognition accuracy with a ten-word vocabulary.
