Laser-Printed Graphene for Self-Charging Wearables and High-Efficiency Battery Electrodes

energyPilotedTRL 5

Imagine printing electronics onto fabric using a laser instead of heavy machinery. This technology turns ordinary clothes into power plants that harvest energy from your body movements to power sensors. It also creates a cleaner, drier way to make battery parts, removing the need for wet chemical baths.

The business problem

What needed solving

Current wearable sensors rely on bulky batteries that require frequent charging and disrupt fabric comfort. Additionally, battery electrode manufacturing remains dependent on costly, wet-chemical processes.

The solution

What was built

A laser-assisted production method for graphene coatings on textiles and a dry-electrode fabrication process for Li-ion batteries.

Who can put this to work

Wearable Technology
SME
Target: Smart clothing manufacturer

If you are a smart clothing manufacturer dealing with bulky batteries that ruin fabric feel — this project developed self-charging e-textiles that harvest energy from movement. This allows for battery-less sensors integrated directly into the garment.

Energy Storage
enterprise
Target: Li-ion battery producer

If you are a battery producer dealing with expensive and polluting wet-coating processes — this project developed a dry electrode approach for next-generation batteries. This aligns with the 2030 European SET-plan for more sustainable production.

Healthcare IoT
mid-size
Target: Medical device developer

If you are a medical device developer dealing with the need for continuous patient monitoring without frequent charging — this project developed micro-flexible supercapacitors coupled with energy harvesters. This provides a constant power source for wireless health sensors.

Frequently asked

Quick answers

How does this affect production costs?

The project uses low-cost raw materials and a one-step laser-assisted process to ensure cost-effective production of energy devices.

Can this be produced at an industrial scale?

Yes, the project is integrating the process into a roll-to-roll pilot line to move from lab-scale to large-scale implementation.

What is the IP status of the technology?

The methodology is implemented by blending IPR-protected technologies already held by the consortium partners.

How does it integrate with existing IoT systems?

The self-charging textiles act as a human-body-centric interface that transmits sensor signals wirelessly to the IoT.

What is the timeline for deployment?

The project runs from 2023-10-01 to 2027-03-31, aiming to reach TRL 5 or higher.

Consortium

Who built it

The consortium is heavily industry-weighted with a 55% industry ratio, comprising 6 companies (including 6 SMEs) and 5 research/academic partners. This strong commercial presence across 6 European countries suggests a high focus on market viability and industrial scaling rather than pure academic research.
