Description

Wearable technologies and electronic skins are revolutionizing healthcare, soft-robotics, and human-machine interaction, driving the need for flexible and sustainable electronics. Laser-induced graphene (LIG) has emerged as a promising material due to its simple fabrication process via laser scribing on carbon-based materials. Recent advancements enable LIG production on eco-friendly substrates like paper, wood, and textiles, reducing environmental impact while maintaining graphene-like electrical conductive properties. Thereby these biodegradable materials can also be upcycled into LIG-based electronic devices, supporting a circular economy and advancing sustainable electronics.

This project aims to develop LIG-based physical sensors, like temperature sensors, by laser scribing on eco-friendly cellulose acetate substrates. The objectives focus on optimizing laser parameters such as power, speed, and focus distance to enhance electrical properties and pattern quality, ultimately realizing eco-friendly wearable technologies.

Your Tasks:

• Conduct literature research to familiarize with state-of-the-art LIG research.
• Experiment with laser scribing to create conductive patterns on eco-friendly substrates.
• Optimize laser parameters for electrical performance and pattern fidelity.
• Design, fabricate, and characterize the LIG-based physical sensors using the developed technique.

Work Place:

• Campus Nord, IAI (Gebäude 445) - Practical work in Laboratory

Language(s):

• English
