Dracula Technologies at The Things Conference 2025
On September 23–24 in Amsterdam, Dracula Technologies and truvami will be at The Things Conference to present innovative solutions for the logistics industry.
At Booth A3, visitors can discover how our organic photovoltaic (OPV) cells power the truvami Smart Label entirely with light. This means battery-free energy, where devices can self generate electricity and operate continuously thanks to light energy harvesting. With our organic photovoltaics technology, smart labels become a self powered electric generator—a sustainable alternative that enables self generated energy and reduces reliance on traditional batteries.
As a green energy partner, Dracula Technologies demonstrates how OPV organic photovoltaics and organic photovoltaic devices are redefining the future of logistics.
Expert sessions you won’t want to miss
Achieve Maintenance-Free Asset Tracking through Organic Photovoltaic (Jérome Vernet VP Sales, Chiara Koopmans CEO)

The truvami Smart Label, powered by Dracula Technologies’ organic photovoltaics (OPV), is redefining what’s possible in intelligent traceability. By harvesting energy from ambient light, the Smart Label achieves battery free energy and operates as a true self generating power supply—no manual maintenance required.
This ultra-thin and sustainable solution significantly lowers total cost of ownership while ensuring reliable self produced electricity. Designed for scalability, it unlocks new opportunities across logistics, retail, healthcare, and beyond.
With organic photovoltaic devices from Dracula Technologies, energy independence becomes a reality—setting a new standard for smarter, greener, and maintenance-free asset tracking.
Raising the Bar for Indoor Light Energy Harvesting (Roelof Koopmans, Dracula Technologies)

At Dracula Technologies, we continue to push the limits of organic photovoltaics (OPV), achieving new levels of performance for battery free energy solutions. Our technology enables devices to self generate energy from light, setting new standards for sustainable power in IoT.
During the event, we’ll share customer success stories that highlight real-world impact and showcase how our organic photovoltaic devices are shaping the future of connected applications. We’ll also provide an update on the latest developments within the LoRa Alliance, where energy harvesting is taking a central role in enabling maintenance-free, scalable IoT solutions.
Current State of Energy Harvesting & LoRaWAN® – Panel with Dracula Technologies, Dryad Networks, MClimate, Semtech

The future of billions of IoT devices relying on batteries is neither sustainable nor realistic. LoRaWAN®, as one of the most energy-efficient wireless protocols, is naturally aligned with energy harvesting technologies that enable battery free and autonomous devices. To accelerate this transition, the LoRa Alliance® has created a dedicated Energy Harvesting Taskforce. Its members collaborate to showcase the effectiveness of self powered devices and to promote the adoption of currently available battery free LoRaWAN solutions.
During this panel, we will discuss the current state of energy harvesting in IoT, share insights into organic photovoltaicsand other self generating power technologies, and explore the future developments that will drive the large-scale adoption of sustainable, maintenance-free IoT devices.
