Battery-free IoT devices powered by indoor light harvesting technology

digitalTestedTRL 5

Imagine a tiny sensor that never needs a battery change because it drinks the light from your office lamps. Instead of heavy silicon panels, it uses a flexible, printable plastic-like material that is much better at catching dim indoor light. It's like giving a gadget a permanent, invisible power cord connected to the room's lighting.

Target: Low-power wearable or home gadget manufacturer

If you are a gadget maker dealing with short device lifespans due to non-rechargeable batteries — this project developed a roll-to-roll assembly process for light energy harvesters to create self-sufficient electronics.

Frequently asked

Quick answers

How does this reduce the cost of IoT deployments?

It eliminates the need for periodic battery replacement and maintenance, which is critical as the number of IoT devices is estimated to reach 30 billion by 2027.

Can this be produced at an industrial scale?

Yes, the project focuses on demonstrating integrated roll-to-roll assembly, which is a cost-effective method for large area manufacturing.

What is the IP or licensing status of the technology?

Based on available project data, specific licensing terms are not listed, but the project is led by an SME (EPISHINE AB) with a consortium of 13 partners.

How does it integrate with existing electronics?

The project develops flexible hybrid electronics, combining organic photovoltaics with printed electronics to create integrated IoT devices.

What is the timeline for the demonstration?

The project is active from September 1, 2024, to August 31, 2027.

Consortium

Who built it

The consortium is heavily industry-driven, with 9 industrial partners (69% ratio) and 7 SMEs, indicating a strong push toward commercialization. With 13 partners across 8 countries, the project balances academic research (2 universities, 2 research centers) with the practical manufacturing capabilities of SMEs and larger firms.
