In this paper, we investigate a case towards the emerging Internet of Batteryless Things by leveraging the latest advances in energy harvesting for self-powered computing. We present the design and implementation of a self-powered IoT system for ...

Batteryless energy harvesting platforms are gaining popularity as a way to bring next-generation sensing and edge computing devices to deployments previously limited by their need for batteries. Energy harvesting enables perpetual, maintenance-free ...

The concept of ambient IoT was introduced by 3GPP to describe low-cost, self-powered, or battery-free sensor nodes, which may reach up to 10 trillion units in the future. By replacing chemical batteries in many standalone IoT devices, we can achieve ...

For edge IoT devices, ambient energy harvesting offers a batteryless energy solution by collecting environmental energy. When using a ReRAM crossbar to simulate spiking neural networks (SNNs), a single ReRAM crossbar is often not capable of simulating ...

We present EXTREMIS, a compile-time pipeline that improves energy consumption of battery-less devices by ensuring that memory operations occur at the most efficient device frequency setting. Different memory operations incur different energy consumption ...

Intermittent computing systems allow devices to operate under unstable and weak power conditions. When a device performing long tasks is interrupted due to power instability, a checkpoint mechanism is used to save data to non-volatile memory before the ...

Accurate and failure-resilient timekeeping is crucial for time-sensitive sensing operations and task scheduling in batteryless systems. The main challenge lies in measuring the duration of power failures precisely. Remanence timekeepers offer a simple ...

Energy harvesting techniques can lead to a more sustainable operation of low-powered IoT devices, i.e., they can operate batteryless, have a low CO2 footprint, and are easily maintained (no battery replacement). With that in mind, we propose LIGHTED, a ...

To reduce battery maintenance costs and environmental impact, there is a growing interest in harvesting energy for IoT networks. Evaluating intermittent software in a large, distributed network is challenging due to the variable efficiency of energy ...
