The GREENsPACK project is a multidisciplinary research initiative focused on developing environmentally friendly smart packaging solutions. Here are the key details about the project:

Project Overview:

GREENsPACK aims to create fully biodegradable and low-cost sensing tags for smart packaging of perishable goods like food and medicine. The project is funded by the Swiss National Science Foundation (SNF) under their BRIDGE Discovery program.

Key Features:

  • Biodegradable Materials: The project utilizes eco-friendly, biodegradable materials to address issues related to food quality and climate change

  • Chipless Technology: The sensing tags are designed to be chipless, making them ultra-low cost and simple to produce

  • Additive Manufacturing: The tags are additively manufactured by printing onto cost-effective cellulosic substrates

  • Wireless Sensing: The project develops wireless and chipless environmental sensing systems based on resonant circuits

Technical Aspects:

The GREENsPACK project focuses on several scientific challenges:

  • Developing new sensing materials

  • Integrating sensors into wireless biodegradable structures

  • Creating sensors for identification, temperature, and relative humidity monitoring
