Dracula Technologies showcased energy harvesting solutions

 

At the LOPEC 2025 in Munich, Germany, the French specialist company for energy harvesting solutions presented their newest product: LAYER, which reduces battery reliance and enhances maintenance efficiency for connected devices.

As IoT deployment expands, the challenge of powering numerous sensors is addressed by LAYER, an organic photovoltaic (OPV) thin film that generates energy from ambient light, making them more sustainable and scalable. To ensures a continuous power supply for IoT sensors, Dracula Technologies showcased LAYER Vault, a 2-in-1 solution integrating energy harvesting and storage in a single flexible film. This technology enables reliable operation even in low-light environments and reduces the need for frequent battery replacements. Both were presented live.

Demonstrations with partners highlighted the possible applications on how the new technology integrates into real-world situations:

• Atmosic: A battery-free remote control integrating Atmosic’s ultra-low-power ATM33 chip and LAYER energy-harvesting module. The remote can function entirely on indoor light, allowing for compact designs and eliminating battery changes.
• STMicroelectronics: LAYER technology integrated into the STM32U0 microcontroller enables full energy autonomy. The OPV module’s ability to harvest energy from ambient light powers the device across various applications, including industrial and medical devices, eliminating the need for traditional batteries.
• Orioma: The LobX-2 is an autonomous infrared camera for monitoring air quality, humidity, movement, and temperature, based on the activity and number of occupants in a room. Utilising LAYER for continuous energy supply, the camera operates maintenance-free for up to 15 years, using wireless LoRaWAN communication for data transmission.
• CoolR: The Vista-Z infrared camera from CoolR is an IoT camera designed for the consumer goods industry. Powered by LAYER OPV modules, it is completely energy autonomous, requiring no cables or electrical outlets. With its AI system, it continuously transmits real-time information and alerts on shelf stock availability, enabling clients to efficiently allocate their resources.
• truvami: A Smart Label for logistics and asset tracking, featuring LAYER-powered energy harvesting. The label automatically sends location, temperature, and motion data to the cloud, enhancing supply chain management efficiency without the need for manual scanning.
• Miromico: The miro Insight Lux monitors indoor air quality with precision, detecting CO2 levels using NDIR technology, alongside temperature, humidity, and ambient. It integrates cutting-edge OPV technology, ensuring reliable operation without the need for batteries even in low-light indoor environments. This innovation not only enhances energy self-sufficiency but also eliminates ongoing battery replacement costs, making it a cost-effective and sustainable choice.

The need for high-efficiency organic photovoltaics is growing. Indoor OPVs provide an attractive energy solution for IoT devices due to their deployability, reliability, and power density. With billions of IoT devices expected indoors, custom-made OPVs are essential for seamless integration. Inkjet printing offers scalability and design flexibility. Herein we demonstrate the challenge of scaling from lab to industry to produce fully inkjet-printed, efficient IOPV cells and modules.
