Walkthrough shows how IoT OEMs can easily use ambient energy to reduce environmental impact and customer OpEx, staying ahead of potential legislation
Louvain-la-Neuve, Belgium – February 25, 2025 – As environmental regulations tighten and battery waste becomes a growing concern, IoT original equipment manufacturers (OEMs) are increasingly seeking sustainable, low-maintenance power solutions. In an exclusive walkthrough hosted by Silicon Labs as part of its 2025 Tech Talks webinar series, e-peas, a global leader in energy harvesting power management ICs, showcased how its new energy harvesting shields, combined with Silicon Labs’ Explorer Kit, make developing battery-free Ambient IoT devices simple and cost-effective.
First Look: AEM13920 and AEM00300 Energy Harvesting Shields
This webinar featured the first unboxing of e-peas’ new AEM13920 and AEM00300 energy harvesting shields. These components integrate with Silicon Labs’ new Explorer Kit (featuring the EFR32xMG22E SoC) to deliver:
-
Ultra-fast cold start capability
-
Highly efficient deep sleep modes
-
Seamless compatibility with multiple energy sources
These features support reliable operation of Ambient IoT systems across a wide range of applications, including smart buildings, asset tracking, and industrial automation.
Step-by-Step Development Support for OEMs
The webinar provides a complete walkthrough for developers, including:
-
Real-time demonstrations
-
Best-practice design recommendations
-
System-level energy efficiency insights
Additionally, registered attendees receive access to a GitHub repository with supporting documentation and software tools to help accelerate time to market for battery-free, self-sustaining IoT devices.
Why Ambient IoT Matters Now
“The shift to Ambient IoT is no longer optional—it’s urgent,” said Bruno Damien, Ecosystem Marketing Director at e-peas. “The cost and environmental burden of battery-powered devices are no longer sustainable. Our partnership with Silicon Labs helps developers close the knowledge gap and embrace a smarter, cleaner approach to powering IoT.”
Governments are also taking action. A 2023 EU positioning paper calls for greater adoption of energy harvesting in IoT design, stating that “batteries should outlive the devices they power.”
The EU-funded EnABLES project further estimates that 78 million IoT batteries will be discarded in 2025 alone—highlighting the urgency for scalable, sustainable alternatives.
AEM13920: Multi-Source Energy Management
The AEM13920 shield is designed to harvest energy from a range of intermittent and continuous sources:
-
Photovoltaic (solar)
-
Thermal gradients
-
RF waves
-
Inductive and piezoelectric systems
It delivers up to 90% energy-transfer efficiency and supports programmable output voltage, making it ideal for Bluetooth, Zigbee, and custom protocols.
AEM00300: Optimized for Pulsed Energy Harvesting
The AEM00300 shield is engineered to efficiently capture and store random pulses of energy in the microjoule range. Its smart architecture stabilizes the energy flow, making it perfect for unpredictable environments where conventional power methods fail.
Powering the Future of IoT
This webinar also featured Silicon Labs’ multi-protocol IoT solutions, further enhancing the possibilities for developers building connected, maintenance-free systems.
Now in its sixth year, the Silicon Labs Tech Talks series continues to bring together industry leaders to share best practices and advanced tools in wireless and power management technologies.
