e-peas is transforming the future of IoT with its advanced energy harvesting PMIC (Power Management Integrated Circuit) technology, enabling truly battery-free IoT devices.
In a recent ipXchange interview during Embedded World 2024, e-peas demonstrated how its energy harvesting PMICs power real-world IoT applications running entirely on harvested energy — no batteries required.
Live Demo: LoRaWAN IoT Node Powered by Harvested Energy
At the event, e-peas collaborated with Murata, Semtech, and Dracula Technologies to showcase a working LoRaWAN IoT application powered solely by ambient light.
The setup featured:
-
A miniature PCB with LoRaWAN capability
-
Four IoT end nodes transmitting data to a Semtech gateway
-
Power sourced entirely from harvested ambient light
Applications demonstrated included:
-
Livestock tracking
-
Smart building monitoring
This cutting-edge use case proves that energy harvesting PMIC technology can eliminate the need for traditional batteries in wirelessly connected IoT products.
How e-peas Energy Harvesting PMIC Powers Battery-Free IoT
At the heart of the demo was the e-peas AEM10920 energy harvesting PMIC, which manages:
-
Energy harvesting from ambient sources
-
Energy storage for backup operation
-
Efficient energy delivery to IoT devices
Key capabilities:
-
Enables IoT devices to function even during extended periods of darkness
-
Optimizes power storage and output for consistent operation
With 17 different energy harvesting PMICs in its portfolio, e-peas offers the industry’s most comprehensive solution for designing battery-free IoT devices.
Multiple Energy Sources — Maximum Design Flexibility
e-peas energy harvesting PMICs support a wide range of energy sources:
