Imagine a thin, flexible sticker that drinks up indoor light and turns it into electricity. Instead of using heavy, polluting lithium batteries that die every few years, this technology uses organic inks to power small electronics. It's like giving your smart home gadgets a permanent, green power source that fits any shape.
IoT devices rely on lithium-ion batteries that are environmentally damaging to mine and have short lifespans of only 2-3 years. This creates a recurring waste and maintenance problem for smart home ecosystems.
A flexible, inkjet-printed organic photovoltaic (OPV) module and a compatible flexible supercapacitor for energy storage.
If you are a smart home device manufacturer dealing with short battery lifespans of 2 to 3 years — this project developed the LAYER® module that harvests ambient light to provide a sustainable energy alternative. It is less than 5 mm thick and can be customized to any shape.
If you are a wireless sensor producer dealing with the high environmental cost of lithium mining — this project developed a 100% green OPV module. It offers a power conversion efficiency of 25% under indoor illumination to keep sensors running without battery replacements.
If you are a smart switch brand dealing with bulky battery compartments — this project developed a flexible, inkjet-printed energy layer. It is 3 times lower cost than traditional options and integrates a supercapacitor for sustainable storage.
Based on available project data, the LAYER® technology is 3 times lower cost than the alternatives it replaces.
Yes, the project validated the use of inkjet printing and identified two industrial partners with the expertise to ensure large-scale transfer of ink formulations.
Based on available project data, the technology is branded as LAYER®, but specific licensing terms are not detailed in the report.
The module is flexible, customizable in shape and size, and less than 5 mm thick, making it easy to integrate into various IoT device forms.
While typical lithium-ion batteries last 2 to 3 years or 300 to 500 cycles, the LAYER® is designed as a sustainable alternative to replace this limited battery usage.
The project is led by a single French SME, Dracula Technologies, which acted as the sole partner. This lean structure allowed for rapid internal iteration of the inkjet printing process and direct validation of industrial partners for scaling, maintaining a 100% industry ratio.
