Smart Buildings with LoRaWAN®

Reading time : 2 min | 02/19/2025

Most IoT applications still rely on traditional batteries, leading to high maintenance costs and significant environmental impact due to battery waste. In large-scale deployments, particularly in Smart Buildings using technologies like LoRaWAN, this approach quickly becomes unsustainable.

A recent paper by Beecham Research highlights Energy Harvesting as a viable solution to these challenges. By capturing energy from ambient light, low-power devices can operate efficiently without the need for frequent battery replacements. This reduces costs, eliminates waste, and ensures long-term reliability.

At Dracula Technologies, we are pioneering this transition with our LAYER® technology. Our inkjet-printed photovoltaic modules harvest energy from low-intensity indoor light, offering a flexible, cost-effective, and eco-friendly alternative—without the use of rare earth materials.

Discover how Energy Harvesting can transform your IoT applications.
